Abstract
Aiming at the demand of simultaneous receiving in dual beam for satellite communication terminal antennas,a K-band dual beam receiving phased array on satellite communication is designed.The flat-panel active phased array architecture,which integrated antenna on board(AOB),is adopted to achieve high density integration of antenna,R model,beamforming network,beam controller and power supplier.A 1 024-element receiving phased array antenna prototype is manufactured and tested,which shows that the antenna is able to scan to±60° and the gain-to-noise(G/T)is no less than 4.22 dB/K.The proposed phased array has the characteristic of low profile,light weight,low cost,convenient for mass production,and is instructive for engineering research on multi-beam flat-panel active phased array.关键词
