Description

technical field [0001] The invention relates to the communication field, in particular to an integrated tile active phased array antenna. Background technique [0002] The phased array antenna is the key core component of the phased array radar / communication system, which directly determines the performance of the entire phased array radar / communication system, and occupies a large proportion in the cost, volume, weight and power consumption of the entire system . The architecture of active phased array antennas can be roughly divided into two types: brick type and tile type according to the circuit assembly method. Brick-type active phased array antennas are simple in design, easy to install, and have better heat dissipation capabilities, but they are heavy and bulky, which to some extent limits the development and application of active phased array antennas. The tile active phased array antenna is highly integrated and usually adopts a stacked structure, which can greatl...
