基于瓦片式T/R组件的高集成度Ku频段有源相控阵天线设计OA

Based on a tile architecture,a highly integrated Ku-band active phased array antenna capable of±70° beam scanning is designed.The active phased array consists of a microstrip patch panel array antenna,transmit/receive(T/R)modules,beam control and feed networks,and heat sinks.The T/R modules are designed in a tile configuration,with each channel capable of simultaneously prestoring amplitude and phase compensation codes for both the receive and transmit branches.Compared with traditional brick-type T/R modules,this design significantly reduces the dimension along the RF signal propagation direction while achieving monolithic integration of 128 channels,thereby realizing miniaturization,lightweight,and high reliability.The antenna array adopts a triangular lattice arrangement,which improves the gain by approximately 1 dB at a 60° scan angle compared with conventional rectangular lattice structures.This active phased array also features the advantages of low profile,thin and lightweight design,and simple assembly/disassembly.
