Description

technical field

[0001] The invention belongs to antenna technology in the fields of measurement, control and communication, and relates to a two-dimensional electronic scanning antenna, in particular to a two-dimensional electronic scanning antenna based on a radio frequency switch. Background technique

[0002] For an antenna with a fixed beam, there is a contradiction between antenna gain and beam coverage. Generally speaking, the higher the antenna gain, the smaller the angular range covered by the antenna beam. Therefore, in order to solve the above-mentioned contradiction, two methods are usually adopted: one is to install the antenna on the servo device, and realize the mechanical scanning of the antenna beam by the rotation of the servo mechanism, but the servo mechanism greatly increases the volume and weight of the antenna, and The scanning speed of the antenna beam is restricted by the servo mechanism; another way is to use the phased array antenna to realize the ...
