Detailed Description

Embodiments of the present application will now be described more fully hereinafter with reference to the accompanying drawings, in which it is shown, however, that the embodiments shown are merely exemplary, and not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description.

As described in the background section, how to meet the requirement of antenna isolation while achieving miniaturization of an antenna is an urgent problem to be solved. For example, how to meet the requirement of antenna isolation while achieving miniaturization of MIMO antennas.

Based on the above, the present application provides an antenna module, as shown in fig. 1, fig. 1 is a schematic structural diagram of the antenna module provided by the present application, where the antenna module includes:

An antenna unit 100, the antenna unit 100 including a first antenna 110 and a second antenna 120 disposed at intervals.

An isolation unit 200, the isolation unit 200 being disposed between the first antenna 110 and the second antenna 120. The operating parameters of the isolation unit 200 can be adjusted according to the operating parameters of the antenna unit 100, so as to isolate the target signal between the first antenna 110 and the second antenna 120.

It should be noted that, the antenna modules in different devices have corresponding operating frequency bands, for example, mobile phones, wireless routes, etc. all operate in a specified frequency band. Thus, the first antenna 110 and the second antenna 120 may receive and transmit signals within the operating frequency range corresponding to the device in which they are located, for example, the first antenna 110 may receive and radiate radio frequency signals within the operating frequency range, and the second antenna 120 may also receive and radiate radio frequency signals within the operating frequency range.

When the first antenna 110 is located in the far-field polarization range of the second antenna 120, or when the second antenna 120 is located in the far-field polarization range of the first antenna 110, or when the first antenna 110 and the second antenna 120 are located in the far-field polarization range of each other, in other words, the first antenna 110 is located in the main radiation direction of the second antenna 120, the second antenna 120 is located in the main radiation direction of the first antenna 110, and the first antenna 110 and the second antenna 120 are located in the main radiation direction of each other, this will result in a strong coupling effect between the first antenna 110 and the second antenna 120, with a low isolation, and thus, the two will affect each other's signal receiving and transmitting.

However, with miniaturization of the antenna module, the space between the antennas in the antenna module is reduced, which means that there is a problem of low isolation between the first antenna 110 and the second antenna 120, which affects the operation of the first antenna 110 and the second antenna 120. As can be seen from the foregoing and fig. 1, the antenna module provided by the present application sets the isolation unit 200 between the first antenna 110 and the second antenna 120, where the working parameters of the isolation unit 200 can be adjusted correspondingly with the working parameters of the antenna unit 100 to isolate the radio frequency signals between the first antenna 110 and the second antenna 120, that is, the isolation unit 200 can reduce the influence of the first antenna 110 on the second antenna 120 and reduce the influence of the second antenna 120 on the first antenna 110, and can improve the isolation between the first antenna 110 and the second antenna 120, so that the isolation of the antenna unit 100 can meet the requirement, and has the target isolation, that is, the interference between the first antenna 110 and the second antenna 120 in the antenna unit 100 is low, for example, the interference is 0 or is within the allowed range. Of course, in other embodiments, due to different scenario requirements, the isolation unit 200 may be configured to isolate only at least one of the high frequency signal, the low frequency signal, or the intermediate frequency signal between the first antenna 110 and the second antenna 120, i.e., the target signal isolated by the isolation unit 200 may be a radio frequency signal in the target frequency band between the first antenna 110 and the second antenna 120.

Therefore, the antenna module provided by the application realizes higher isolation of the first antenna 110 and the second antenna 120 through the isolation unit 200, and the isolation is realized without the need of meeting certain requirements on the distance between the first antenna 110 and the second antenna 120, so that the distance between the first antenna 110 and the second antenna 120 can be reduced, further, on the premise of meeting the isolation requirements, the miniaturization of the antenna module can be realized, the size of the antenna module can be doubled, and the length can be only 45mm, so as to meet the miniaturization development trend of terminal electronic equipment.

In addition, the antenna unit 100 in the antenna module operates in a certain corresponding frequency band, and the operating frequency band is divided into a plurality of operating channels, such as a high-frequency operating channel, a low-frequency operating channel or a specific frequency band operating channel, that is, the high-frequency signal, the low-frequency signal and the intermediate-frequency signal can be respectively corresponding to the above-mentioned high-frequency signal, the low-frequency signal and the intermediate-frequency signal, and the antenna unit 100 in the antenna module selects the corresponding operating channel to operate according to the actual requirement, so that the signal frequency of the antenna unit 100 when operating is not fixed but dynamically changed according to the requirement. Based on this, according to the above, the working parameters of the isolation unit 200 in the antenna module provided by the present application can be correspondingly adjusted along with the working parameters of the antenna unit 100, that is, the working parameters of the isolation unit 200 can be changed along with the change of the working parameters of the antenna unit 100, so that even if the signal frequency of the antenna unit 100 is dynamically changed during working, the isolation unit 200 can be dynamically adjusted along with the change, thereby realizing a higher isolation between the first antenna 110 and the second antenna 120.

Or because the corresponding working frequency ranges of different types of electronic devices are different, the electronic devices can be at least one of high-frequency signals, low-frequency signals or intermediate-frequency signals, so that the working frequency ranges of the antenna units 100 of the antenna modules of different electronic devices need to be changed accordingly, namely, the working parameters of the antenna units 100 in the antenna modules need to be changed accordingly. The working parameters of the isolation unit 200 in the antenna module of the application can be correspondingly adjusted along with the working parameters of the antenna unit 100, that is, the isolation unit 200 can be correspondingly adjusted according to the signal frequency band corresponding to the electronic equipment where the isolation unit 200 is located, so that one isolation unit 200 can realize higher isolation of the antenna units 100 of different types of electronic equipment, and one antenna module can be suitable for different types of electronic equipment, thus the antenna module has stronger practicability and wide application prospect.

Based on the foregoing embodiments, in one embodiment of the present application, as shown in fig. 2, fig. 2 is a schematic structural diagram of an antenna module provided by the present application, where the isolation unit 200 includes:

an isolation structure 210, the isolation structure 210 is configured to receive radio frequency signals of the first antenna 110 and the second antenna 120, that is, receive a target signal between the first antenna 110 and the second antenna 120.

The adjusting circuit 220 is electrically connected to the isolation structure 210, and is configured to cooperate with the isolation structure 210 to adjust an operating frequency band and/or an operating channel of the isolation unit 100, and to connect radio frequency signals received by the isolation structure 210 and radiated by the first antenna 110 and the second antenna 120 to ground. Therefore, the adjusting circuit 220 can cooperatively adjust at least one of the operating frequency band and the operating channel of the isolation unit 200 with the isolation structure 210, so that the operating parameter of the isolation unit 200 can be correspondingly adjusted along with the operating parameter of the antenna unit 100, and the target signal between the first antenna 110 and the second antenna 120 is accessed to the ground.

Based on the above, the isolation structure 210 may receive the target signal between the first antenna 110 and the second antenna 120, and the adjusting circuit 220 may mutually coordinate and adjust the working parameter of the isolation unit 200, so that the working parameter of the isolation unit 200 may be correspondingly adjusted along with the working parameter of the antenna unit 100, and the adjusting circuit 220 may further connect the target signal between the first antenna 110 and the second antenna 120 received by the isolation structure 210 to the ground, that is, the isolation structure 210 may connect the radio frequency signal radiated by the first antenna 110 in the direction of the second antenna 120 to the ground, and connect the radio frequency signal radiated by the second antenna 120 in the direction of the first antenna 110 to the ground, thereby reducing the mutual coupling between the first antenna 110 and the second antenna 120, and thus, the antenna module may have a higher isolation between the first antenna 110 and the second antenna 120, and may meet the requirement of a higher isolation.

Based on the above embodiments, in one embodiment of the present application, as shown in fig. 3, fig. 3 is a schematic structural diagram of an antenna module provided by the present application, and the adjusting circuit 220 includes:

The plurality of first adjusting branches 221, which are formed by at least one capacitive element C and/or at least one inductive element L, are used for extending the length of the isolation structure 210, i.e. the adjusting circuit 220 comprises a plurality of first adjusting branches 221, which are formed by at least one capacitive element C, or comprises a plurality of first adjusting branches 221, which are formed by at least one inductive element L, or comprises a plurality of first adjusting branches 221, which are formed by at least one capacitive element C and at least one inductive element L. It should be noted that, the structure of the first adjusting branch 221 in fig. 3 is only an example of the first adjusting branch 221, and the specific structure of the first adjusting branch 221 is not limited.

The switch 222 is capable of conductively connecting the corresponding first adjustment branch 221 with the isolation structure 210 in response to the target control signal, so that the isolation unit 200 adjusts to the target operating frequency band and/or the target operating channel.

As can be seen from the above description, the adjusting circuit 220 includes a plurality of first adjusting branches 221, and the switch 222 can connect the corresponding first adjusting branches 221 to the isolation structure 210 in a conductive manner in response to the control signal, and the first adjusting branches 221 can be used to extend the length of the isolation structure 210, that is, the adjusting circuit 220 can connect the corresponding first adjusting branches 221 to the isolation unit 210 in a conductive manner in response to the target control signal, so as to extend the length of the isolation structure 210 to a target length.

Since the operating frequency band/channel of the isolation structure 210 is related to its length, the longer the length, the higher the frequency, and conversely the shorter the length, the lower the frequency. Therefore, the adjusting circuit 220 can connect the corresponding first adjusting branch 221 with the isolation unit 210 in a conductive manner in response to the target control signal, and extend the length of the isolation structure 210 to a target length, so that the isolation unit 200 can be adjusted to the target operating frequency and/or the target operating channel in response to the control signal.

It should be noted that, the isolation structure 210 is the same as the first antenna 110 and the second antenna 120 and is made of metal, so that the lengths of the isolation structures 210 are different, which means that the capacitances and/or inductances of the isolation structures 210 are different, which results in different frequencies of the isolation structures 210. Therefore, when the first tuning branch 221 formed by the at least one capacitive element C and/or the at least one inductive element L is connected in an electrically conductive manner to the isolation structure 210, the inductance and/or the capacitance of the isolation structure 210 is increased, i.e. the length of the isolation structure 210 is increased, so that the first tuning branch 221 formed by the at least one capacitive element C and/or the at least one inductive element L can be used to extend the length of the isolation structure 210. It should be noted that, the number of the capacitive element C and the inductive element L in the first adjusting branch 221 and the parameters of the capacitive element C and the inductive element L in the first adjusting branch 221 need to be set according to the operating frequency or the operating channel of the antenna module.

As known from the above, the length of the isolation structure 210 is inversely proportional to the frequency thereof, and the first adjusting branch 221 may extend the length of the isolation structure 210, so if the length of the isolation structure 210 corresponding to the maximum value of the operating frequency of the antenna module is a preset length, the actual length of the isolation structure 210 may be smaller than the preset length, and thus the length of the isolation structure 210 in the antenna module provided by the present application may be smaller, thereby contributing to miniaturization of the antenna module.

For example, if the operating frequency band of the antenna module, that is, the operating frequency band of the antenna unit 100 includes a first operating frequency band, a second operating frequency band, and a third operating frequency band, and the center frequency of the first operating frequency band is greater than the center frequency of the second operating frequency band, the center frequency of the second operating frequency band is greater than the center frequency of the third operating frequency band, then the preset length is a length corresponding to the center frequency in the first operating frequency band, and the length of the isolation structure 210 may be less than the preset length. Based on this situation, the plurality of first adjustment branches 221 may include three first adjustment branches 221, which are respectively referred to as a first sub-adjustment branch, a second sub-adjustment branch, and a third sub-adjustment branch, where the inductance or capacitance of the first sub-adjustment branch is smaller than the inductance or capacitance of the second sub-adjustment branch, and the inductance or capacitance of the second sub-adjustment branch is smaller than the inductance or capacitance of the third sub-adjustment branch, so that if the antenna unit 100 operates in the first operating frequency band, the switch 222 connects the first sub-adjustment branch to the isolation structure 210 in a conductive manner, if the antenna unit 100 operates in the second operating frequency band, the switch 222 connects the second sub-adjustment branch to the isolation structure 210 in a conductive manner, and if the antenna unit 100 operates in the third operating frequency band, the switch 222 connects the third sub-adjustment branch to the isolation structure 210 in a conductive manner, so that the operating parameters of the isolation unit 200 can be adjusted accordingly according to the operating parameters of the antenna unit 100, and the first antenna 110 and the second antenna 120 meet the isolation requirement.

It should be noted that, the inductance or capacitance of the first sub-adjustment branch is known to be smaller than the inductance or capacitance of the second sub-adjustment branch, and the inductance or capacitance of the second sub-adjustment branch is known to be smaller than the inductance or capacitance of the third sub-adjustment branch. If the parameters of the capacitive elements C and the inductive elements L on the different first regulation branch 221 are both the same and the first regulation branch 221 is provided with one of the capacitive elements C and the inductive elements L, then the number of capacitive elements C and inductive elements L on the first sub-regulation branch is smaller than the number of capacitive elements C and inductive elements L on the second sub-regulation branch, and the number of capacitive elements C and inductive elements L on the second sub-regulation branch is smaller than the number of capacitive elements C and inductive elements L on the third sub-regulation branch. Or if the parameters of the capacitive element C and the number of inductive elements L on the different first regulation branch 221 are the same and the first regulation branch 221 is provided with one of the capacitive element C and the inductive element L, the capacitance value of the capacitive element C and the inductance value of the inductive element L on the first sub-regulation branch are smaller than the capacitance value of the capacitive element C and the inductance value of the inductive element L on the second sub-regulation branch, and the capacitance value of the capacitive element C and the inductance value of the inductive element L on the second sub-regulation branch are smaller than the capacitance value of the capacitive element C and the inductance value of the inductive element L on the third sub-regulation branch. Or, the first adjusting branch 221 is provided with both the capacitive element C and the inductive element L, so that parameters and/or numbers of the capacitive element C and the inductive element L on different first adjusting branches 221 need to be adjusted according to actual situations, so that the inductance or capacitance of the first sub-adjusting branch is smaller than the inductance or capacitance of the second sub-adjusting branch, and the inductance or capacitance of the second sub-adjusting branch is smaller than the inductance or capacitance of the third sub-adjusting branch.

On the basis of the above embodiment, in one embodiment of the present application, as further shown in fig. 3, the antenna module further includes:

the first control unit 300 is in signal connection with the switch 222, and is capable of sending a corresponding target control signal to the switch 222 according to the obtained working parameter of the antenna unit 100, so that the working parameter of the isolation unit 200 is consistent or inconsistent with the working parameter of the antenna unit 100.

Based on the above, in one embodiment of the present application, if the working parameters of the isolation unit 200 are consistent with the working parameters of the antenna unit 100, the isolation unit 200 can receive the radio frequency signals radiated by the first antenna 110 and the second antenna 120, that is, can receive the target signals between the first antenna 110 and the second antenna 120, and further can access the target signals between the first antenna 110 and the second antenna 120 to the ground through the adjusting circuit 220, so that the isolation between the first antenna 110 and the second antenna 120 is higher, and the isolation requirement between the first antenna 110 and the second antenna 120 can be ensured while the antenna module is miniaturized. It should be noted that, the operating parameters of the isolation unit 200 and the operating parameters of the antenna unit 100 are consistent, and not the operating parameters of the isolation unit 200 and the operating parameters of the antenna unit 100 must be completely consistent, but the operating parameters of the isolation unit 200 and the operating parameters of the antenna unit 100 are consistent as much as possible, so that the difference of the operating parameters is within the allowable range, for example, the deviation between the center frequency of the radio frequency signal of the antenna unit 100 and the center frequency of the isolation unit 200 is within the allowable range.

In another embodiment of the present application, if the working parameters of the isolation unit 200 are inconsistent with those of the antenna unit 100, the isolation unit 200 may switch in the rf signal of a specific frequency band between the first antenna 110 and the second antenna 120 to the ground, but the rf signal of the specific frequency band does not belong to the rf signals radiated or received by the first antenna 110 and the second antenna 120, that is, the isolation unit 200 may switch in the rf signal between the first antenna 110 and the second antenna 120 and not belong to the first antenna 110 and the second antenna 120 to the ground, thereby isolating the first antenna 110 and the second antenna 120 from the external signal, so as to avoid the influence of the external environment on the first antenna 110 and the second antenna 120, and improve the working reliability of the first antenna 110 and the second antenna 120.

In another embodiment of the present application, as shown in fig. 4, fig. 4 is a schematic structural diagram of an antenna module provided by the present application, and the adjusting circuit 220 includes:

The second adjusting leg 223, which is composed of at least one capacitive element C and at least one inductive element L, is used to extend the length of the isolation structure 210, i.e. the second adjusting leg 223 may comprise one capacitive element C, or the second adjusting leg 223 may comprise one inductive element L, or the second adjusting leg 223 may comprise at least one capacitive element C and at least one inductive element L.

The second control unit 224 is electrically connected to the second adjustment branch 223, and can control the capacitive element L and/or the inductive element L to adjust to a target capacitance and/or a target inductance according to the obtained working parameter of the antenna unit 100, so that the working parameter of the isolation unit 200 is consistent or inconsistent with the working parameter of the antenna unit 100, in other words, the second control unit 224 can adjust the capacitance value of the capacitive element C and/or the inductance value of the inductive element L according to the working parameter of the antenna unit 100, so that the working parameter of the isolation unit 200 is consistent or inconsistent with the working parameter of the antenna unit 100. Therefore, the difference between the present embodiment and the above embodiment is that the capacitance value of the capacitive element C in the present embodiment can be adjusted and changed, and the inductance value of the inductive element L can be adjusted and changed, that is, the capacitive element C in the present embodiment can be a variable capacitive element, the inductive element L is a variable inductive element, and the capacitive element L and the inductive element L in the above embodiment are elements whose parameters are not changeable. Compared with the above embodiment, the antenna module of this embodiment has only one second adjusting circuit 223 including a variable inductance and/or a variable capacitance, and the circuit structure is simpler and the adjustment and control are more convenient.

It should be noted that, the reason and purpose that the second control unit 224 makes the working parameter of the isolation unit 200 consistent or inconsistent with the working parameter of the antenna unit 100 according to the working parameter of the antenna unit 100 is the same as the reason and purpose that the first control unit 300 makes the working parameter of the isolation unit 200 consistent or inconsistent with the working parameter of the antenna unit 100 according to the working parameter of the antenna unit 100, which are not described herein.

It should be noted that, the second control unit 224 may control the capacitive element C and/or the inductance element L to be adjusted to the target capacitance and/or the target inductance according to the obtained operation parameter of the antenna unit 100, and may be that if the second adjustment branch 223 includes at least one capacitive element C, the second control unit 224 controls the capacitive element C to be adjusted to the target capacitance according to the obtained operation parameter of the antenna unit 100; if the second adjusting branch 223 includes at least one inductance element L, the second control unit 224 controls the inductance element L to adjust to the target inductance value according to the obtained operation parameter of the antenna unit 100; if the second adjustment branch 223 includes at least one capacitive element C and at least one inductive element L, the second control unit 224 controls the capacitive element C to be adjusted to a target capacitive value according to the obtained operation parameter of the antenna unit 100, or the second control unit 224 controls the inductive element L to be adjusted to a target inductive value according to the obtained operation parameter of the antenna unit 100, or the second control unit 224 controls the capacitive element C to be adjusted to a target capacitive value according to the obtained operation parameter of the antenna unit 100, and the second control unit 224 controls the inductive element L to be adjusted to a target inductive value according to the obtained operation parameter of the antenna unit 100.

For example, as shown in fig. 5 to 7, fig. 5 is a graph of the change in the isolation between the first antenna 110 and the second antenna 120 when the isolation unit 200 is not provided for the first antenna 110 and the second antenna 120, fig. 6 and 7 are graphs of the change in the isolation between the first antenna 110 and the second antenna 120 when the inductance values l=22nh and l=36nh of the isolation unit 200 are respectively provided, the ordinate represents the isolation, the abscissa represents the frequency, and 1,2, 3,4,5, and 6 represent the isolation when the antenna unit 100 is at different operating frequencies. As can be seen from fig. 5 to 7, when the isolation unit 200 is not provided between the first antenna 110 and the second antenna 120, the isolation between the first antenna 110 and the second antenna 120 is low, and when the isolation unit 200 is provided, the isolation between the first antenna 110 and the second antenna 120 is effectively improved. As can be further seen from fig. 6 and fig. 7, the isolation between different operating frequencies of the antenna unit 100 varies with the frequency of the isolation unit 200, so that the target signal between the first antenna 110 and the second antenna 120 can be isolated by correspondingly adjusting the operating parameters of the isolation unit 200 with the operating parameters of the antenna unit 100.

It should be noted that, in practical application, the first control unit 300 may be an EC or a BIOS on the motherboard, and the EC or the BIOS on the motherboard may send a corresponding target control signal to the switch according to the working parameter of the antenna unit 100, or the first control unit 300 may also be a micro controller MCU disposed in the antenna module, for example, the MCU is disposed between a module chip of the antenna module and an antenna structure (an antenna unit and an isolation unit), and obtains the working parameter of the antenna unit 100 through the MCU, and sends a corresponding target control signal to the switch according to the working parameter of the antenna unit 100, so that the working parameter of the isolation unit 200 is consistent with the working parameter of the antenna unit 100 or is consistent with the working parameter of the antenna unit 100. The second control unit 224 may also be a motherboard EC or BIOS, or a micro controller MCU disposed in the antenna module, so as to control the capacitive element and/or the inductive element to adjust to a target capacitance value and/or a target inductance value according to the obtained working parameters of the antenna unit 100, so that the working parameters of the isolation unit 200 are all or partially consistent with the working parameters of the antenna unit 100.

On the basis of the foregoing, in an embodiment of the present application, as shown in fig. 8, fig. 8 is a schematic structural diagram of an antenna module provided by the present application, where the first antenna 110 is a PIFA antenna, and the second antenna 120 is a PIFA antenna, and the PIFA antenna is also called a planar inverted-F antenna. The directions of the first antenna 110 and the second antenna 120 are the same, for example, the first antenna 110 and the second antenna 120 are sequentially arranged along a first direction, the directions of the first antenna 110 and the second antenna 120 are second directions, and the second directions are perpendicular to the first directions.

Based on the above, the first antenna 110 includes the first microstrip line 111, the first microstrip line 111 includes the first high frequency portion 1111 and the first low frequency portion 1112 arranged along the first direction, the first high frequency portion 1111 is used for radiating and receiving the high frequency radio frequency signal, the first low frequency portion 1112 is used for radiating and receiving the low frequency radio frequency signal, the second antenna 120 includes the second microstrip line 121, the second microstrip line 121 includes the second high frequency portion 1211 and the second low frequency portion 1212 arranged along the first direction, the second high frequency portion 1211 is used for radiating and receiving the high frequency radio frequency signal, the second low frequency portion 1212 is used for radiating and receiving the low frequency radio frequency signal, so that the first antenna 110 and the second antenna 120 can radiate and receive the radio frequency signal in a certain high frequency to a certain low frequency range, so that the antenna unit 100 can radiate and receive the radio frequency signal in a certain high frequency to a certain low frequency range, and the antenna module has a wide operating frequency range.

The tail end of the first high-frequency portion 1111 is bent, the tail end of the first low-frequency portion 1112 is bent, and the tail end of the second low-frequency portion 1212 is bent, so that the microstrip lines of the first antenna 110 and the second antenna 120 do not always extend along the first direction, but bend at the tail end, thereby reducing the lengths of the microstrip lines of the first antenna 110 and the second antenna 120 along the first direction without reducing the effective lengths of the first antenna 110 and the second antenna 120, further reducing the size of the space occupied by the first antenna 110 and the second antenna 120, and contributing to miniaturization of the antenna module. And the tail end of the first low frequency portion 1112 is bent, so that the current direction of the tail end of the first low frequency portion 1112 is changed, the signal radiation direction of the tail end is correspondingly changed, and the target signal between the first low frequency portion 1112 and the second high frequency portion 1211 is reduced, so that the mutual coupling between the first low frequency portion 112 and the second high frequency portion 1211 is reduced, and the isolation is improved.

In addition, in the present embodiment, the isolation structure 210 of the isolation unit 200 is disposed between the first low frequency portion 1112 and the second high frequency portion 1211, and the isolation unit 200 is closer to the second high frequency portion 1212, so that the current on the isolation unit 200 can partially act on the second high frequency portion 1212, which is equivalent to a portion of the effective length of the second high frequency portion 1212, so that the tail end of the second high frequency portion 1212 does not need to be bent, and the length of the second high frequency portion 1212 in the first direction is smaller than the length of the first high frequency portion 1112 in the first direction, thereby contributing to miniaturization of the antenna module.

On the basis of the above, in one embodiment of the present application, as further shown in fig. 8, the isolation structure 220 of the isolation unit 200 is an n-type isolation structure, and the opening of the isolation structure 220 is oriented towards the same direction as the F of the first antenna 110 and the second antenna 120, i.e. the shape of the isolation structure 220 is n-type, and the opening of the n-type is oriented towards the same direction as the F of the first antenna 110 and the second antenna 120, i.e. the isolation structure 220 may be a bent structure, and the dimension along the first direction is smaller, so that the space occupied by the isolation structure 220 is smaller, which is helpful for miniaturization of the antenna module. And/or the first antenna 110 includes the first feeding point 113, the second antenna 120 includes the second feeding point 123, and a distance between the first feeding point 113 and the second feeding point 123 is a quarter of an electromagnetic wave wavelength of the antenna unit 110, that is, a distance between the first feeding point 113 and the second feeding point 123 along the first direction may be a quarter of an electromagnetic wave wavelength of the antenna unit 110, so that a distance between the first antenna 110 and the second antenna 120 is small, for example, a distance between the first feeding point 113 and the second feeding point 123 may be 6.5mm, that is, a distance between the first antenna 110 and the second antenna 120 may be 6.5mm, thereby contributing to miniaturization of the antenna module.

As can be seen from the above description, the antenna module of the present application may have an n-type isolation structure 220, or a distance between the first feeding point 113 and the second feeding point 123 is one-fourth of the electromagnetic wave wavelength of the antenna unit 110, or an n-type isolation structure 220, and a distance between the first feeding point 113 and the second feeding point 123 is one-fourth of the electromagnetic wave wavelength of the antenna unit 110, so as to achieve the purpose of miniaturization of the antenna module.

It should be noted that, in order to improve the isolation between the first antenna 110 and the second antenna 120, in addition to the target signal between the first antenna 110 and the second antenna 120 being connected to the ground, the isolation between the first antenna 110 and the second antenna 120 may be improved by diverging the target signal between the first antenna 110 and the second antenna 120. Based on this, the above-described isolation unit 200 may include at least one of an open resonance unit and a sub-wavelength structure, that is, the above-described isolation unit 200 may include an open resonance unit, or may include a sub-wavelength structure, or may include both an open resonance unit and a sub-wavelength structure, so that the metamaterial unit has a negative refractive property, thereby being capable of radiating electromagnetic waves of feed-point radiation.
