Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an antenna unit and electronic equipment.
Background
With the development of the fifth Generation mobile communication (5th-Generation, 5G) system and the wide application of electronic devices, the millimeter wave antenna is gradually applied to various electronic devices to meet the increasing use requirements of users.
At present, millimeter wave antennas in electronic devices are mainly implemented by using an Antenna In Package (AiP) technology. For example, as shown in fig. 1, an array antenna 11 with an operating wavelength of millimeter waves, a Radio Frequency Integrated Circuit (RFIC) 12, a Power Management Integrated Circuit (PMIC) 13 and a connector 14 may be packaged into a module 10 by AiP technology, where the module 10 may be referred to as a millimeter wave antenna module. The antenna in the array antenna may be a patch antenna, a yagi-uda antenna, or a dipole antenna.
However, since the antennas in the array antenna are usually narrow-band antennas (such as the patch antennas listed above), the coverage frequency range of each antenna is limited, but the millimeter wave frequency range planned in the 5G system is usually many, for example, n257(26.5-29.5GHz) frequency range mainly based on 28GHz and n260(37.0-40.0GHz) frequency range mainly based on 39GHz, and the like, so that the conventional millimeter wave antenna module may not cover the mainstream millimeter wave frequency range planned in the 5G system, thereby resulting in poor antenna performance of the electronic device.
Disclosure of Invention
The embodiment of the invention provides an antenna unit and electronic equipment, and aims to solve the problem that the antenna performance of the electronic equipment is poor due to the fact that the frequency range covered by a millimeter wave antenna of the conventional electronic equipment is small.
In order to solve the technical problem, the present application is implemented as follows:
in a first aspect, an embodiment of the present invention provides an antenna unit, where the antenna unit includes: the target insulator, M feeding portions, feeding arm structures and first isolating bodies arranged in the target insulator, and a first grounding body arranged at the bottom of the target insulator; the feeding arm structure comprises M feeding arm units, wherein each feeding arm unit comprises a first feeding arm, a second feeding arm electrically connected with the first end of the first feeding arm, and a third feeding arm electrically connected with the second feeding arm; the second end of the first feed arm in each feed arm unit is electrically connected with different feed parts in the M feed parts, the third feed arms in each feed arm unit in the M feed arm units are electrically connected with each other, the connection points of the electrical connection with each other are current zero points of the M feed arm units, a first isolation body is arranged around the feed arm structure and is electrically connected with the first grounding body, and M is an integer larger than 1.
In a second aspect, an embodiment of the present invention provides an electronic device, where the electronic device includes the antenna unit in the first aspect.
In an embodiment of the present invention, the antenna unit may include: the target insulator, M feeding portions, feeding arm structures and first isolating bodies arranged in the target insulator, and a first grounding body arranged at the bottom of the target insulator; the feeding arm structure comprises M feeding arm units, wherein each feeding arm unit comprises a first feeding arm, a second feeding arm electrically connected with the first end of the first feeding arm, and a third feeding arm electrically connected with the second feeding arm; the second end of the first feed arm in each feed arm unit is electrically connected with different feed portions in the M feed portions, the third feed arms in each feed arm unit in the M feed arm units are electrically connected with each other, the connection points of the electrical connection are current zero points of the M feed arm units, a first isolation body is arranged around the feed arm structure and is electrically connected with the first grounding body, and M is an integer larger than 1. Through the scheme, because the connection point of the third feed arms in each feed arm unit in the M feed arm units, which are electrically connected with each other, is the current zero point of the M feed arm units, the feed arm units can work independently, namely each feed arm cannot be interfered by other feed arm units; the first isolating body is electrically connected with the first grounding body, so that the first isolating body and the first grounding body can form a metal cavity, and the metal cavity can enable electromagnetic waves radiated by the feed arm structure to have directivity; and since the feeding arm unit includes the first feeding arm, the second feeding arm and the third feeding arm, when the feeding portion transmits the ac signal to the feeding arm unit, there may be a plurality of paths of the current passing through the feeding arm unit, for example, a current path formed on the first feeding arm, a current path from the first feeding arm to the second feeding arm, and a current path to the third feeding arm, and so on.

In addition, in the embodiment of the present invention, in order to more clearly illustrate the structure of the antenna unit, the target insulator is not shown in fig. 2.

Alternatively, in the embodiment of the present invention, the structure of the feeding arm structure may be completely symmetrical, that is, the structure (for example, parameters such as width or length) of each of the M feeding arm units is the same; the structure of the feeding arm structure may also be not completely symmetrical (e.g., partially symmetrical), that is, the structures of some feeding arm units in the M feeding arm units are the same; the structure of the feed arm structure may also be asymmetric, i.e. the structure of each of the M feed arm elements is different. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in an embodiment of the present invention, the first feeding arm, the second feeding arm, and the third feeding arm in the feeding arm unit may be integrally formed; or one part can be integrally formed and one part can be assembled; it may also be fully assembled. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
Optionally, in an embodiment of the present invention, the M feeding arm units in the feeding arm structure may be integrally formed (that is, the feeding arm structure is integrally formed); or a part of the feed arms in the M feed arm units may be integrally formed, and another part of the feed arms may be assembled; it is also possible that the feeding arms of the M feeding arm units are all assembled. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In the embodiment of the present invention, when the feeding arm structure is integrally formed, each feeding arm unit is also integrally formed, and the central position of the feeding arm structure may be a connection point where the M feeding arm units are electrically connected to each other, that is, a current zero point of the M feeding arm units.
In addition, the examples in the embodiments of the present invention are each exemplified by an example in which the first feeding arm and the second feeding arm in the M feeding arm units are assembled, and the third feeding arm in the M feeding arm units is integrally formed. For other implementation manners of the M feeding arm units, the implementation manners are similar to the implementation manners in which the first feeding arm and the second feeding arm in the M feeding arm units are assembled and the third feeding arm in the M feeding arm units is integrally formed, and in order to avoid repetition, the embodiment of the present invention is not described again.

In order to more clearly describe the antenna unit and the operating principle thereof provided by the embodiment of the present invention, an example of the operating principle of the antenna unit for transmitting and receiving signals provided by the embodiment of the present invention is specifically described below by taking one antenna unit as an example.
Illustratively, in conjunction with fig. 2, in the embodiment of the present invention, when the electronic device transmits a 5G millimeter wave signal, the signal source in the electronic device may send out an ac signal, and the ac signal may be transmitted to the feeding arm unit in the feeding arm structure through the feeding portion. Then, after the feeding arm unit receives the alternating current signal, the alternating current signal may be radiated outward via the first feeding arm, the second feeding arm, and the third feeding arm in the feeding arm unit. Since the current path of the ac signal through the feeding arm unit may have a plurality of paths, for example, the current path formed on the first feeding arm, the current path from the first feeding arm to the second feeding arm, and then to the third feeding arm, the feeding arm unit may radiate electromagnetic waves of different frequencies to the outside. Therefore, the electronic device can transmit signals with different frequencies through the antenna unit provided by the embodiment of the invention.
As another example, when the electronic device receives a 5G millimeter wave signal, an electromagnetic wave in a space in which the electronic device is located may excite a feeding arm in the feeding arm unit (e.g., a third feeding arm in the feeding arm unit), so that the feeding arm unit may generate an induced current (i.e., an induced ac signal). After the feed arm unit generates the induced alternating current signal, the feed arm unit can input the alternating current signal to a receiver in the electronic device through the feeding part, so that the electronic device can receive a 5G millimeter wave signal transmitted by other devices. That is, the electronic device may receive signals through the antenna unit provided by the embodiment of the present invention.
The performance of the antenna unit provided by the embodiment of the present invention is exemplarily described below with reference to fig. 3.
Exemplarily, as shown in fig. 3, a reflection coefficient diagram of an antenna unit provided in an embodiment of the present invention is shown when the antenna unit operates. When the return loss is less than-6 dB (decibel), the frequency range covered by the antenna unit may be 25.2GHz-41.3GHz, the frequency range may include multiple millimeter wave frequency bands (e.g., n257, n260, and n261), and when the return loss is less than-10 dB, the frequency range covered by the antenna unit may be 26.3GHz-30.1GHz and 36.8GHz-40.1GHz, and the frequency range may also include multiple millimeter wave frequency bands (e.g., n257, n260, and n 261).
It should be noted that, in the embodiment of the present invention, when the return loss of one antenna unit is less than-6 dB, the antenna unit can meet the actual use requirement; when the return loss of one antenna unit is less than-10 dB, the working performance of the antenna unit is more excellent. Namely, the antenna unit provided by the embodiment of the invention can ensure better working performance on the basis of meeting the actual use requirement.
The embodiment of the invention provides an antenna unit, wherein the connection point of the mutual electric connection of the third feed arms in each feed arm unit in the M feed arm units is the current zero point of the M feed arm units, so that the feed arm units can work independently, namely, each feed arm cannot be interfered by other feed arm units; the first isolating body is electrically connected with the first grounding body, so that the first isolating body and the first grounding body can form a metal cavity, and the metal cavity can enable electromagnetic waves radiated by the feed arm structure to have directivity; and since the feeding arm unit includes the first feeding arm, the second feeding arm and the third feeding arm, when the feeding portion transmits the ac signal to the feeding arm unit, there may be a plurality of paths of the current passing through the feeding arm unit, for example, a current path formed on the first feeding arm, a current path from the first feeding arm to the second feeding arm, and a current path to the third feeding arm, and so on.
Optionally, in an embodiment of the present invention, the M feeding portions may penetrate through the first ground body and be insulated from the first ground body.
Specifically, in practical implementation, as shown in fig. 2, a first end of the feeding portion may be electrically connected to a second end of the first feeding arm 2021a in the feeding arm unit, and a second end (not shown in fig. 2) of the feeding portion may pass through the first grounding body and be electrically connected to one signal source in the electronic device (for example, a 5G signal source in the electronic device). In this way, the current of the signal source in the electronic device can be transmitted to the first feeding arm, the second feeding arm and the third feeding arm in the feeding arm unit through the feeding portion, so that the current of the signal source in the electronic device can be transmitted to the antenna unit, and the antenna unit can normally operate.
Optionally, in an embodiment of the present invention, the first feeding arm and the third feeding arm in each feeding arm unit may be perpendicular to the M feeding portions, and the second feeding arm in each feeding arm unit may be perpendicular to the first feeding arm and the third feeding arm.
Exemplarily, as shown in fig. 4, a cross-sectional view of an antenna unit according to an embodiment of the present invention is provided. As can be seen from fig. 4, the first feed arm 2021a and the third feed arm 2021c in the feed arm unit may be perpendicular to the M feed portions 201, and the second feed arm 2021b in the feed arm unit may be parallel to the M feed portions 201, i.e., the second feed arm 2021b in the feed arm unit is perpendicular to the first feed arm 2021a and the third feed arm 2021 c.
Note that, a point a in fig. 4 is used to indicate a connection point at which the respective M feed arm units are electrically connected to each other. In particular, the position may be a central position of the feeder arm structure.
In practice, the position relationship among the first feeding arm, the second feeding arm, and the third feeding arm in the feeding arm unit may also be any other possible position relationship, and may be determined specifically according to actual use requirements, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, since the feeding arm units have different structures, that is, the first feeding arm, the second feeding arm and the third feeding arm in the feeding arm unit have different positional relationships, and the antenna unit may have different working performances, the positional relationships of the first feeding arm, the second feeding arm and the third feeding arm in the feeding arm unit may be set according to the actual use requirement of the antenna unit, so that the antenna unit provided in the embodiment of the present invention may work in a 5G millimeter wave frequency band.
In addition, since the first feeding arm and the third feeding arm in the feeding arm unit are perpendicular to the second feeding arm, the current path on the feeding arm unit can be increased, and thus the frequency band covered by the antenna unit provided by the embodiment of the invention can be expanded.
Alternatively, in the embodiment of the present invention, the feeding arm structure may be disposed at a central position of the target insulator. For example, the center position of the cross section of the target insulator.
Optionally, in an embodiment of the present invention, a distance between the first end of the first feeding arm in each feeding arm unit and a center of the target insulator (specifically, a center of a cross section of the target insulator) may be greater than a distance between the second end of the first feeding arm and the center of the target insulator.
It is to be understood that the distribution direction of the first feeding arm in each feeding arm unit described above in the target insulator may be a direction from the center of the target insulator to the edge of the target insulator.
It should be noted that, the embodiment of the present invention is only exemplified by the case that the distance between the first end of the first feeding arm and the center of the target insulator is greater than the distance between the second end of the first feeding arm and the center of the target insulator, and the embodiment does not set any limit to the present application. In practical implementation, the first feeding arms may be disposed in the target insulator in any possible distribution manner, which may be determined according to practical use requirements, and the embodiments of the present invention are not limited thereto.
Optionally, in this embodiment of the present invention, the M feeding arm units may be four feeding arm units (i.e., M is 4), the four feeding arm units may constitute two feeding arm unit groups, each feeding arm unit group may include two symmetrically disposed feeding arm units, and a symmetry axis of one feeding arm unit group is orthogonal to a symmetry axis of another feeding arm unit group.
In the embodiment of the present invention, since the antenna unit may include two feeding arm unit groups, and each feeding arm unit group includes two feeding arm units, the electronic device may respectively transmit or receive signals through the two feeding arm unit groups in the antenna unit, that is, the MIMO technology may be implemented by the antenna unit provided in the embodiment of the present invention, so that the communication capacity and the communication rate of the antenna unit may be improved, that is, the data transmission rate of the antenna unit may be improved.
It should be noted that, for convenience of description and understanding, the two feeding arm unit groups described above are divided into a first feeding arm unit group and a second feeding arm unit group in the following embodiments. The first feeding arm unit group and the second feeding arm unit group respectively comprise two symmetrically arranged feeding arm units, and the symmetry axis of the first feeding arm unit group is orthogonal to the symmetry axis of the second feeding arm unit group.
Alternatively, in this embodiment of the present invention, the first feeding arm unit group and the second feeding arm unit group may be two feeding arm unit groups with different polarizations. In particular, the first feeding arm unit group may be a feeding arm unit group of a first polarization, and the second feeding arm unit group may be a feeding arm unit group of a second polarization.
Exemplarily, as shown in fig. 5, a top view of an antenna unit in a direction opposite to the Z-axis is provided for the embodiment of the present invention. The first feeding arm unit group may include a first feeding arm unit 20210 and a second feeding arm unit 20211, and the second feeding arm unit group may include a third feeding arm unit 20212 and a fourth feeding arm unit 20213. Wherein the first feeding arm unit group formed by the first feeding arm unit 20210 and the second feeding arm unit 20211 may be a feeding arm unit group of a first polarization (e.g., a feeding arm unit group of a horizontal polarization); the second feeding arm element group formed by the third feeding arm element 20212 and the fourth feeding arm element 20213 may be a feeding arm element group of a second polarization (e.g., a feeding arm element group of a vertical polarization).
It should be noted that, since fig. 5 is a top view of the antenna unit provided by the embodiment of the present invention in the direction opposite to the Z axis, the coordinate system in fig. 5 only illustrates the X axis and the Y axis.
Optionally, in this embodiment of the present invention, the first polarization and the second polarization may be polarizations in different directions.
For example, the first polarization may be +45 ° polarization or horizontal polarization; the second polarization may be-45 ° polarization or vertical polarization.
Of course, in practical implementation, the polarization direction of the first polarization and the polarization direction of the second polarization may be any other possible polarization directions. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.
In the embodiment of the invention, because the current flowing on the feeding arm unit has directivity when the antenna unit works, under the condition that the distribution direction of the first feeding arm in the feeding arm unit in the metal groove is from the center of the target insulator to the edge of the target insulator, the distance between the feeding arm units can be increased, namely the interference between different feeding arm units can be reduced, thereby improving the isolation degree of the antenna unit, namely the polarization purity of the antenna unit can be improved.

Exemplarily, as shown in fig. 6, a schematic diagram of polarization isolation of an antenna unit when the antenna unit provided by the embodiment of the present invention operates is provided. It is assumed that the feeding arm unit group composed of the first feeding arm unit and the second feeding arm unit is a horizontally polarized feeding arm unit group, and the feeding arm unit group composed of the third feeding arm unit and the fourth feeding arm unit is a vertically polarized feeding arm unit group. Then, as shown in fig. 6, the isolation of the antenna unit is less than-115 dB in the full frequency band in which the antenna unit operates (i.e., all frequency bands that the antenna unit can cover). However, the isolation of the antenna unit is-10 dB to meet the actual use requirement, and the smaller the polarization isolation of the antenna unit is, the higher the polarization purity of the antenna unit is, so that the polarization isolation of the antenna unit can be greatly improved by the above arrangement method, and the polarization performance of the antenna unit can be further optimized.
In the embodiment of the present invention, the first feeding arm unit group and the second feeding arm unit group may be two feeding arm unit groups with different polarizations (the first polarization and the second polarization), so that the antenna unit provided in the embodiment of the present invention may form a dual-polarized antenna unit, and thus, the wireless connection capability of the antenna unit may be improved, and thus, the probability of the communication disconnection of the antenna unit may be reduced, that is, the communication capability of the antenna unit may be improved.

In the embodiment of the invention, because the punching process is simple, the processing process of the first isolating body can be simplified by arranging the through hole in the first isolating body and arranging the metal column in the through hole, so that the processing difficulty of the antenna unit can be reduced.
It should be noted that, in the embodiment of the present invention, the smaller the distance between two adjacent metal pillars in the N metal pillars is, the better the effect of the electromagnetic wave radiated by the feeding arm structure of the N metal pillars (i.e., the first isolator) to the direction of the first isolator is.
