A wideband tiled active array is proposed for multifunction application.The active array consists of eight sub-arrays.In order to achieve high integration,scalability,and low profile,a three-layer tiled architecture is adopted,with the antenna elements,T/R modules and time-delay multifunctional modules vertically interconnected,and they are all assembled by cold plates.Exter-nal power supply and control are distributed to the T/R modules through the time-delay multifunc-tional modules.The test results of the active array show that within the instantaneous bandwidth of 4 GHz and the scanning range of±45°,the beam pointing deviation is nearly 1/10 of the beam width through full time-delay compensation.
