Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a dual-polarization array antenna. Background Art

[0002] Antennas are widely used in radio systems such as communication, broadcasting, television, radar and navigation. They play a role in propagating radio waves and are essential devices for effectively radiating and receiving radio waves. The definition of array antennas: Array antennas are special antennas that are composed of no less than two antenna units arranged regularly or randomly and obtain predetermined radiation characteristics through appropriate excitation. The radiated electromagnetic field of the array antenna is the sum of the radiation fields of each unit that constitutes the antenna array. Since the position of each unit and the amplitude and phase of the feeding current can be adjusted independently, the array antenna has various functions that cannot be achieved by a single antenna. Some high-isolation dual-frequency dual-polarization array antennas are achieved by increasing the distance between the two antennas, reducing surface wave coupling and reducing spatial coupling; for example, the patent with publication number CN217035996U discloses a high-isolation dual-frequency dual-polarization 5G millimeter wave array antenna, including a base, four face corners at the top of the base are provided with mounting holes, and the top of the base is fixedly connected with a mounting seat. The user inserts the plug plates at both ends of the array antenna body into the slot, and then rotates the first threaded rod. The first threaded rod can be moved through the first threaded hole. The moved first threaded rod can insert the fixing plate through the connecting slot into the fixing slot through the movable plate, thereby tightening the array antenna body. At the same time, the array antenna body can be prevented from shaking under the action of the spring and the pillar. The user rotates the second threaded rod, and the protective cover can be fixed through the side plate and the second threaded hole. The array antenna body can be protected by the protective cover. The device is convenient for users to disassemble and assemble the array antenna body, but when using it, it is still necessary to manually rotate the threaded rod to achieve the tightening effect, and it is necessary to press the array antenna body downward to align the fixing slot with the fixing plate. However, if the pressing force is too large or too small, the fixing slot and the fixing plate will be offset, resulting in the inability to rotate the threaded rod, thereby affecting the installation of the array antenna.

[0003] To this end, the utility model provides a dual-polarization array antenna. Utility Model Content
