【 摘 要 】

A large aperture membrane phased array antenna with an array antenna and transmit/receive (T/R) modules is presented for geosynchronous Earth orbit synthetic aperture radar applications. Its scanning beams can cover ±8° with ignorable grating lobes within its visible area. By utilising the coplanar reintegration technique of multichips, compact and light-weight T/R modules can be achieved. A scaled model is demonstrated and characterised experimentally. Measured results validate the feasibility and efficiency of the design method for the membrane phased array antenna.
