Description

Technical Field

[0001] The utility model relates to the technical field of phased array antennas, in particular to a phased array antenna with good heat dissipation. Background Art

[0002] Phased array antennas are antennas that change the shape of their radiation patterns by controlling the feeding phase of the radiating elements in the array antenna. Controlling the phase can change the direction of the maximum value of the antenna pattern to achieve the purpose of beam scanning.

[0003] The phased array antenna generates a large amount of heat and has a poor heat dissipation effect. After the heat dissipation module is used for a long time, a large amount of dust and flocs will adhere to the air intake filter, reducing the heat dissipation efficiency. If the phased array antenna is cleaned directly without removing the air intake filter, it is easy to cause water to enter the phased array antenna and be damaged. However, the existing air intake filter is generally fixed with multiple bolts, which is not convenient for quick disassembly and assembly, and the disassembly and assembly is time-consuming and labor-intensive. Therefore, we have launched a phased array antenna with good heat dissipation. Utility Model Content
