The utility model discloses a dual-polarized radiation unit, please refer to fig. 1, which includes a radiation member 10, a reflection member 30, and an excitation structure 20, wherein the radiation member 10 is provided with a radiation window 11; the reflector 30 is stacked with the radiator 10; a plurality of excitation structures 20 are arranged along the edge of the radiation window 11; wherein the excitation structure 20 is connected to a feed source for radiating radio frequency signals out of the radiation window 11, and the reflector 30 reflects the signals out of the radiation window 11.
By making the radiation element 10 into a hollow structure and using the hollow structure as the radiation window 11, when the dual-polarized radiation unit radiates a signal, the excitation structure 20 and an external feed source connected to the excitation structure 20 form an electromagnetic field, an energy portion of the electromagnetic field is directly radiated from the radiation window 11, and another portion is reflected by the reflector 30 and then radiated from the radiation window 11, thereby forming a radiation field required for transmitting the signal. Since the signal radiated from the radiation window 11 is perpendicular to the radiation element 10, the radiation direction of the dual-polarized radiation unit is changed when the signal is radiated. In practical application, a plurality of dual-polarized radiation units arranged in an array are generally used for radiating signals at the same time, so that in this embodiment, by changing the radiation direction of the dual-polarized radiation units, signals are prevented from being radiated from the periphery of the dual-polarized radiation units, and thus, adjacent dual-polarized radiation units are mutually influenced.
The reflecting member 30 is disposed opposite to the radiating member 10, so that the signal radiated to the reflecting member 30 from the radiation window 11 can be reflected back to the radiation window 11, and the signal directly radiated outward from the radiation window 11 can be combined into a radiation field, so that the radiation direction of the dual-polarized radiation unit has unity, that is, all the signals are radiated out from the radiation window 11. In this embodiment, the distance between the reflecting member 30 and the radiation window 11 is typically within one wavelength of the signal frequency.
In addition, during the signal radiation process, a part of the energy of the electromagnetic field is still radiated from the outer edge of the radiation member 10, and forms a radiation field together with the energy radiated from the radiation window 11. In this embodiment, the size of the radiation window 11 and/or the size of the radiation element 11 may be adjusted to reduce the energy radiated from the outer edge of the radiation element 10 by the electromagnetic field, so as to ensure that the energy radiated from the outer edge of the radiation element 10 is controlled within an allowable range, so as to reduce the influence of the radiation element 10 on the peripheral radiation, where it should be noted that the size of the radiation window 11 is smaller than the distance between two adjacent dual-polarized radiation units.
It can be understood that, since the excitation structure 20 needs to form an electromagnetic field for radiation on the radiation member 10, the reflection member 30 needs to reflect energy of the electromagnetic field to the radiation window 11. Therefore, the radiation element 10 and the reflection element 30 are made of conductive materials. In this embodiment, the radiation element 10 and the reflection element 30 may be made of conductive metals of different materials, such as iron and copper; further, the conductive carbon compound may be used. The present embodiment includes, but is not limited to, the above-mentioned solutions, and can be made of any material with conductive property.
The utility model discloses technical scheme is through directly set up on the radiation piece 10 radiation window 11, radiation piece 10 can follow the signal when radiating the signal radiation window 11 radiates away perpendicularly. Moreover, the radiation window 11 is disposed in parallel with the reflector 30, so that when a part of the signal which is not radiated is reflected by the reflector 30, the signal can be vertically reflected from the radiation window 11. Therefore, the radiation direction of the dual-polarized radiation unit during signal radiation is changed, radiation is only carried out in the vertical direction of the radiation piece, and the mutual influence between the radiation from the periphery of the radiation piece 10 and the surrounding dual-polarized radiation unit is avoided.
Specifically, the excitation structure 20 includes a feed slot 21, a tuning window 22 and a feed transmission line 23, where the feed slot 21 is formed on the radiating element 10; the feed gap 21 communicates the radiation window 11 and the adjusting window 22; the two poles of the feed transmission line 23 are directly connected or coupled with the two sides of the feed gap 21.
The feeding slot 21 and the adjusting window 22 are formed on the radiating element 10, that is, the feeding slot 21 and the adjusting window 22 are through slots with different shapes on the radiating element, and two ends of the feeding slot 21 are respectively communicated with the radiating window 11 and the adjusting window 22. The feeding transmission line 23 is a radio frequency transmission line, such as a microstrip line, a coaxial cable, a stripline, a slot line, a coplanar waveguide line, and the like. One end of the feed transmission line 23 is connected to an external feed source, and the other end is connected to the radiating elements 10 on both sides of the feed gap 21 (the radiating element 10 can be used as the ground of the feed transmission line 23), that is, the inner and outer or equivalent inner and outer conductors of the feed transmission line 23 are electrically connected to the radiating elements 10 on both sides of the feed gap 21, respectively.
It should be noted that, in this embodiment, the feeding transmission line 23 may cross over the feeding slot 21 by a direct connection manner to connect two ends of the feeding slot 21; in addition, the coupling connection may be implemented by connecting with one end of the feed slot 21 and extending to the other end of the feed slot 21 to form a non-contact connection (open circuit), that is, suspending above or below the other end of the feed slot 21. It is understood that the feeding transmission line 23 can be separately connected to one end of the feeding slot 21 to realize a coupling connection.
After the feed transmission line 23 is connected with the feed gap 21, the feed transmission line 23 transits the signal sent from the feed source to the feed gap 21, and transmits the signal to the radiation window 11 along the feed gap 21, and the signal is radiated out through the radiation window 11. This embodiment preferably causes signal blocking when the distance between the feed slots 21 is too narrow, and the signal cannot be transmitted into the radiation window 11, so that the width of the feed slot 21 should not exceed the half wavelength of the highest frequency when the feed slot 21 is provided.
In the above process, in order to prevent the signal of the feeding transmission line 23 from being transmitted to the wrong direction, the feeding gap 21 cannot transmit the signal to the radiation window 11, so that the signal cannot be successfully radiated, therefore, by providing the adjustment window 22 with a small area at the other end of the feeding gap, a part of the signal can be transmitted to the adjustment window 22 along the feeding gap 21, and is radiated out through the adjustment window 22, thereby realizing adjustment of the signal of the feeding transmission line 23 transiting to the feeding gap 21, and avoiding the signal from being blocked in the feeding gap 21 due to the transmission of the feeding transmission line 23 to the wrong direction. Thereby ensuring that the feed slot 21 and the radiation window 11 radiate signals smoothly. In this embodiment, the adjustment window 22 may be a circle, an ellipse, or any other smooth shape, or may be any polygon, and the adjustment window 22 includes but is not limited to the above-mentioned solutions, and the shape of the boundary of the conductor constituting the adjustment window 22 is not limited.
In particular, the feeding transmission line 23 is arranged inside the radiating element 10. When the radiating element 10 is thick, in order to enable the feed transmission line 23 to normally transit signals into the feed gap 21, the feed transmission line 23 may be embedded inside the radiating element 10, so that the feed transmission line 23 can directly pass through two ends of the feed gap 21 to connect two ends of the feed gap 21. In the present embodiment, the feeding transmission line 23 is embedded in the radiating element 10, so that the feeding transmission line 23 can be protected to some extent from being damaged.
The feeding transmission line 23 is not necessarily arranged in parallel with the radiating element 10, and there may be an angle between the feeding transmission line 23 and the radiating element 10, for example, the feeding transmission line 23 is arranged perpendicular to the radiating element 10. It is understood that the feeding transmission line 23 and the feeding slot 21 may not be arranged in a perpendicular (90 °) manner, and other angle arrangements also fall within the protection scope of the present embodiment.
Specifically, the dual-polarized radiation unit includes four excitation structures 20, and the four excitation structures 20 are disposed around the radiation element 10. In the present embodiment, taking the radiating element 10 as a rectangle, four excitation structures 20 are respectively disposed at four corners of the radiating element 10, and in the four excitation structures 20, the transmission direction of the feeding transmission line 21 of each excitation structure 20 is sequentially rotated by ninety degrees, so that signals are transmitted in four different directions. In addition, the radiation member 10 may also be circular, and when the radiation member 10 is circular, four excitation structures 20 may be respectively disposed on the upper, lower, left, and right portions of the radiation member 10. It suffices that four of the excitation structures 20 are evenly distributed around the radiating element 10.

As an embodiment, referring to fig. 11, the dual-polarized radiation unit further includes a power divider 40, and the power divider 40 is connected to two excitation structures 20 diagonally disposed on the radiation window 11. In this embodiment, the transmission directions of the four feeding transmission lines 23 are sequentially rotated by ninety degrees, the transmission directions of the feeding transmission lines 23 of the two diagonally arranged excitation structures 20 are rotated by one hundred eighty degrees, that is, the transmission directions of the feeding transmission lines 23 on the two diagonally arranged excitation structures 20 are opposite, and when the feeding transmission lines 23 with the opposite directions feed in the same direction, for example, the two feeding transmission lines 23 are connected to form one port through the power divider (one-to-two power divider), different polarization directions can be formed for radiation. In the present embodiment, the two feeding transmission lines 23 at different positions are connected by the power divider 40 to generate radiation in horizontal, vertical, -45 °, +45, left-hand circular polarization, right-hand circular polarization, and other polarization forms.
It should be noted that the power divider may be externally connected through the feeding transmission line 23, or may be directly fabricated on the radiating element 10, and the radiating element 10 may be fabricated by various materials such as a metal plate, a PCB, plastics, or a combination of various materials listed.

For example, radiation in a polarization form such as left-hand circular polarization, right-hand circular polarization, or the like can be generated by connecting two of the feed transmission lines 23 at different positions using a 90 ° 3dB directional coupler, a 180 ° 3dB directional coupler, or the like.
Specifically, the dual-polarized radiation unit further includes a shielding wall 50, and the shielding wall 50 is disposed between the radiation member 10 and the reflection member 30; or, the shielding wall 50 is disposed around the radiation member 10, and the shielding wall 50 is made of a conductive material.

In this embodiment, the shielding wall 50 may be further disposed around the radiation element 10, and the radiation window 11, the feed gap 21, and the adjustment window 23 are filled with a non-conductor, so that a closed space is formed between the radiation element 10 and the reflection element 30, and external dust, water stain, and the like, which carry static electricity or other substances, are prevented from entering the dual-polarized radiation unit to affect the radiation signal.
In addition, the position of the shielding wall 50 can be adjusted according to the requirement of the dual-polarized radiation unit for performance adjustment, please refer to fig. 4-6, for example, the shielding wall 50 can also be connected with the radiation member 10 or the reflection member 30; or is arranged at a distance from the radiation member 10 or the reflection member 30; or the shielding wall 50 may be disposed only at one side between the radiation member 10 and the reflection member 30, and the other direction is completely opened, etc. In this embodiment, the shielding wall 50 may be configured in a circular, oval or other curved form, or may be formed by multiple line segments that are symmetrical or asymmetrical, that is, the cross sections with different heights may have different sizes, and the line segments forming the cross sections may be completely connected together or partially separated, and a gap is formed on the wall surface of the shielding wall 50.
