Description
Technical Field
The present invention relates to the field of electronic products, and in particular, to an antenna structure and an electronic device.
Background
At present, electronic equipment is influenced by the display screen occupation ratio, and the clearance is smaller and smaller under the environment of an antenna. The metal rod is adopted as an antenna, the shape of the antenna is simple, but the variability of the antenna is far inferior to that of a Flexible Printed Circuit (FPC) or Laser-Direct-structuring (LDS) antenna. In order to make the antenna in the electronic device compatible with multiple frequency bands, a mode of separately disassembling the antenna radiation arms corresponding to different frequency bands can be adopted, that is, the antennas in different frequency bands have different radiation arms, but for some slot antennas, because the adjacent antenna radiation arms are closer to each other, the coupling is stronger, thereby affecting the performance of the antenna.
Disclosure of Invention
The embodiment of the invention provides an antenna structure and electronic equipment, and aims to solve the problem that the performance of an antenna is influenced when the distance between adjacent antenna radiation arms is relatively close.
In order to solve the technical problem, the invention is realized as follows:
in a first aspect, an embodiment of the present invention provides an antenna structure, including:
the antenna comprises a first feed source and a first radiation arm, wherein the first feed source is connected with the first radiation arm; the antenna structure works in a radiation mode of a first frequency band through the first radiation arm;
the second feed source is connected with the second radiation arm; the antenna structure works in a radiation mode of a second frequency band through the second radiation arm;
a gap is formed between the first radiation arm and the second radiation arm, the distance of the gap is smaller than or equal to a preset threshold value, and the length of the first radiation arm is not equal to the target length;
an oscillating circuit is arranged on the first radiation arm at a first distance from the gap; wherein the target length is: n (λ/4), the first distance being: k (λ/4), N is a positive integer, and λ is a wavelength corresponding to the second frequency band.
In a second aspect, an embodiment of the present invention further provides an electronic device, including the antenna structure described above.
In the above scheme of the present invention, the energy coupled to the first radiating arm by the second radiating arm is filtered by the oscillating circuit, so that the ground return path of the antenna structure working in the radiation mode of the second frequency band is reduced, the radiation boundary condition of the radiation mode of the second frequency band is achieved, and the efficiency in the radiation mode of the second frequency band is improved. This avoids affecting the antenna performance even when the first and second radiating arms are relatively close in distance.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides an antenna structure, including:
the antenna comprises a first feed source 11 and a first radiation arm 12, wherein the first feed source 11 is connected with the first radiation arm 12; the antenna structure operates in a radiation mode of a first frequency band through the first radiation arm 12;
a second feed 21 and a second radiation arm 22, wherein the second feed 21 is connected with the second radiation arm 22; the antenna structure operates in a radiation mode of a second frequency band via the second radiating arm 22;
a gap is formed between the first radiation arm 12 and the second radiation arm 22, the distance of the gap is smaller than or equal to a preset threshold, and the length of the first radiation arm 12 is not equal to a target length;
an oscillating circuit 31 is arranged on the first radiating arm 12 at a first distance from the gap; wherein the target length is: n (λ/4), the first distance being: k (λ/4), N is a positive integer, and λ is a wavelength corresponding to the second frequency band.
Optionally, the gap is filled with a non-metallic material.
Alternatively, the oscillation circuit 31 is connected to a common ground. In this way, the energy coupled to the first radiating arm 12 by the second radiating arm 22 can be filtered to the common ground through the oscillating circuit 31, so that the ground return path of the antenna structure operating in the radiation mode of the second frequency band is reduced, the radiation boundary condition of the radiation mode of the second frequency band is reached, and the efficiency of the radiation mode of the second frequency band is improved.
Optionally, the preset threshold may be 1.5mm, and the distance of the gap may range from 1.2mm to 1.5 mm. In this way, even in the case of a small gap distance, the energy of the second radiating arm 22 can be prevented from being coupled to the first radiating arm 12 by the oscillating circuit 31, so that the coupling can be prevented from being reduced by increasing the gap distance, and the antenna structure can be advantageously reduced in an excessive space.
Optionally, the first radiating arm 12 is provided with a first connection point, a second connection point, and a third connection point; the first connection point is located at one end of the first radiation arm 12 close to the gap, and the oscillation circuit 31 is connected to the first connection point; the second connection point is located at one end of the first radiation arm 12 far away from the gap, and the second connection point is grounded; the third connection point is located between the first connection point and the second connection point, and the first feed 11 is connected to the third connection point.
As in fig. 1, L2 indicates the distance from the first connection point to the gap, i.e., the first distance; l3 denotes the distance between the first connection point and the second connection point; the first radiating arm 12 has a length of the sum of L2 and L3.
Optionally, a fourth connection point and a fifth connection point are provided on the second radiation arm 22; the fourth connection point is located at one end of the second radiation arm 22 close to the gap, and the second feed source 21 is connected to the fourth connection point; the fifth connection point is located at an end of the second radiating arm 22 away from the slot, and the fifth connection point is grounded.
As in fig. 1, L1 denotes the distance from the fifth connection point to the slot, i.e. the length of the second radiating arm 22.
When the first radiating arm 12 is closer to the second radiating arm 22 (e.g., less than or equal to 1.5mm), and L2+ L3 ≠ N (λ/4), that is, the length of the first radiating arm 12 does not satisfy the radiation boundary condition of the second frequency band, there may be a problem that the radiation energy in the radiation mode of the second frequency band is coupled to the first radiating arm 12, which results in a decrease in efficiency in the radiation mode of the second frequency band. In this case, the filter circuit disposed at the first position on the first radiation arm 12 filters out energy coupled to the first radiation arm 12 in the radiation mode of the second frequency band, so that efficiency in the radiation mode of the second frequency band can be improved.
Wherein L2+ L3 ≠ N (λ/4), N ≠ 1, 2, 3 … K …, i.e., there is a K value such that K (λ/4) < (L2+ L3) < (K +1) × (λ/4), so that a position of L2 ═ K (λ/4) is selected on the first radiation arm 12 to satisfy the radiation critical condition in the radiation mode of the second frequency band; the value K may be determined according to the total length of the first radiating arm 12, for example, K (λ/4) should be smaller than the total length of the first radiating arm 12, and ensure the radiation performance in the radiation mode of the first frequency band.
Alternatively, the distance from the connection end of the first radiating arm 12 to the slot of the oscillator circuit 31, i.e., the first distance L2, may be selected to be one quarter of the wavelength corresponding to the second frequency band, i.e., L2 ═ λ/4.
For example: the frequency coverage of the first frequency band may be: 700MHz to 960 MHz; the frequency coverage of the second frequency band may be: 2490 MHz-2690 MHz or 3300 MHz-3800 MHz; the first distance L2 between the oscillator circuit 31 and the gap may be 2.5mm to 3.5 mm. Preferably, the first distance may be 3 mm.
Specifically, as an implementation manner, the frequency coverage range of the first frequency band is: 700MHz to 960MHz, the frequency coverage of the second frequency band is as follows: 2490 MHz-2690 MHz, or 3300 MHz-3800 MHz, the length of the first radiating arm 12 (sum of L2 and L3) may be 50mm, and the distance from the connection end of the first radiating arm 12 with the first feed 11 to the gap may be 30 mm; the length (L1) of the second radiating arm 22 may be 15mm, and the distance from the connection end of the second radiating arm 22 to the second feed 21 to the gap may be 10 mm.
It should be noted that the frequency coverage ranges corresponding to the first frequency band and the second frequency band are only exemplary, and the setting manner of the oscillation circuit in the embodiment of the present invention may also be applied to radiation modes of other frequency bands, which is not limited in the embodiment of the present invention.
Further, the lengths of the first radiation arm 12 and the second radiation arm 22, and the positions of the first feed 11 and the second feed 21 are also according to an exemplary illustration under the frequency coverage range corresponding to the first frequency band and the second frequency band, that is, the lengths of the first radiation arm 12 and the second radiation arm 22, and the positions of the first feed 11 and the second feed 21 may be set according to a required frequency coverage range corresponding to the first frequency band and the second frequency band, which is not limited in the embodiment of the present invention.
Optionally, the antenna structure further includes: a switch module 13; one end of the switch module 13 is connected with the first feed source 11, and the other end of the switch module 13 is grounded.
For example: the first radiating arm 12 is used for radiating low-frequency signals, such as frequency coverage ranges: under the condition of 700 MHz-960 MHz, the switch module 13 is a low-frequency tuning switch, and plays a role of low-frequency switching; the low-frequency tuning switch comprises at least two connection states, and different connection states correspond to different frequency bands in the frequency coverage range.
Optionally, according to at least one of the above embodiments, the oscillation circuit 31 is an LC oscillation circuit.
Wherein, within the frequency coverage range of the second frequency band, the oscillating circuit 31 is capacitive.
In this way, the oscillation circuit 31 exhibiting capacitance is used for filtering, so as to filter the energy coupled to the first radiation arm 12 by the second radiation arm 22, reduce the ground return path of the antenna structure operating in the radiation mode of the second frequency band, achieve the radiation boundary condition of the radiation mode of the second frequency band, and improve the efficiency in the radiation mode of the second frequency band. This avoids affecting antenna performance even when the first and second radiating arms 12 and 22 are relatively close together.
As an implementation: the oscillation circuit 31 includes: a first inductor and a first capacitor;
the first end of the first inductor is connected to the first end of the first capacitor, one of the second end of the first inductor and the second end of the first capacitor is connected to the first radiating arm 12, and the other of the second end of the first inductor and the second end of the first capacitor is grounded.
Specifically, the oscillating circuit 31 includes a first inductor and a first capacitor connected in series; one end of a first inductor and one end of a first capacitor which are connected in series are connected to the first radiation arm 12, and the other end is grounded; that is, one end of the first inductor is connected to the first radiating arm 12, the other end is connected to the first capacitor, and the other end of the first capacitor is grounded; or one end of the first capacitor is connected to the first radiating arm 12, the other end is connected to the first inductor, and the other end of the first inductor is grounded.
In this embodiment, energy coupled from the second radiation arm 22 to the first radiation arm 12 in the radiation mode of the second frequency band can be filtered out by the LC oscillator circuits connected in series and setting the oscillation frequency of the LC oscillator circuits, so that the antenna performance is prevented from being affected when the distance between the first radiation arm 12 and the second radiation arm 22 is relatively short; in a certain space, the oscillation circuit 31 in the scheme can give consideration to frequency bands with a frequency coverage range of 700MHz to 960MHz, a frequency coverage range of 2490MHz to 2690MHz and a frequency coverage range of 3300MHz to 3800MHz, and can effectively improve the antenna layout space.
As another implementation: as shown in fig. 2, the oscillation circuit 31 includes: a second inductor, a second capacitor and a third inductor;
the first end of the second inductor and the first end of the second capacitor are grounded, the second end of the second inductor and the second end of the second capacitor are respectively connected with the first end of the third inductor, and the second end of the third inductor is connected with the first radiating arm 12.
In this embodiment, the oscillation circuit 31 is formed by connecting the second inductor in parallel with the second capacitor and then connecting the second inductor in series with the third inductor, so that the oscillation circuit 31 has a self-resonant pole and a zero point, and can easily realize a frequency band with a frequency coverage range of 700MHz to 960MHz, a frequency coverage range of 2490MHz to 2690MHz, and a frequency coverage range of 3300MHz to 3800MHz, so that the frequency bands with the frequency coverage range of 700MHz to 960MHz, the frequency coverage range of 2490MHz to 2690MHz, and the frequency coverage range of 3300MHz to 3800MHz are more balanced.
Optionally, the inductance parameter of the third inductor may be 1nH, the capacitance parameter of the second capacitor may be 1pf, and the inductance parameter of the second inductor may be 60 nH; in this way, the self-resonance of the second inductor and the second capacitor can be set near 700MHz, so as to reduce the influence on the low frequency, the third inductor has the function of loading the frequencies from 700MHz to 3800MHz into a capacitive device, and the capacitor has a filtering function on the high frequency, so that the energy coupled to the first radiating arm 12 by the second radiating arm 22 can be directly transferred to the common ground, so that the ground return path in the radiation mode of the second frequency band is reduced, and therefore, the sum of L1, L2 and L3 of the resonant arm in the radiation mode of the second frequency band is changed into the sum of L1 and L2, so that the boundary condition in the radiation mode of the second frequency band is met, and the antenna efficiency of the radiation mode of the second frequency band can be improved.
In addition, the oscillating circuit 31 in this scheme has a self-resonant pole and a zero point, and has a larger capacitance compared with a series LC oscillating circuit, and can better filter the energy coupling from the second radiating arm 22 to the first radiating arm 12 to the common ground, thereby improving the antenna efficiency of the radiation mode of the second frequency band, and further improving the effective utilization rate of the antenna.
Optionally, in order to avoid the energy on the second radiating arm 22 from being coupled to the first radiating arm 12, the oscillating circuit needs to be capacitive in the frequency band of the second frequency, and in addition to the examples given above for the oscillating circuit, a combination of sets of capacitors and inductors may be used, for example: in one embodiment, two sets of LC series-connected oscillation circuits are connected in parallel, so that a capacitance is exhibited at a frequency band where energy needs to be filtered, a specific structure of the oscillation circuit is determined, and a setting position of the oscillation circuit is determined according to a wavelength corresponding to the frequency band where energy needs to be filtered, so as to meet a radiation boundary condition of the required frequency band.
The embodiment of the invention also provides electronic equipment which comprises the antenna structure in at least one embodiment.
