Description

technical field [0001] The invention relates to the field of antennas, in particular to a dual-frequency dual-polarization plate antenna applied to a wireless local area network. Background technique [0002] Most of the existing dual-frequency dual-polarized plate antennas of the wireless local area network use two antennas (antennas in the 2.4G frequency band and antennas in the 5G frequency band) to be installed in one antenna shell. High cost, difficult debugging, not suitable for mass production and interference between the two antennas, poor product use, lack of market competitiveness; a small number of dual-frequency dual-polarization plate antennas cannot solve the problem of low Wave and good directivity and other issues, it is difficult to meet the application of wireless LAN base station equipment in wireless network coverage. [0003] In the application of the forming technology of the dual-frequency dual-polarization plate antenna of the existing wireless local...

Problems solved by technology

[0005] In the existing dual-frequency dual-polarized plate antenna of the wireless local area network, the radiating oscillator cable of the 5G frequency band basically uses a 141-50 tinned cable. The outer diameter of this cable reaches 3.52mm. Small and the feeder cable is too thick, which brings great inconvenience to the fixing of the antenna vibrator on the reflector and the cable welding operation, which is not conducive to the large-scale production of products
