Compact L- & C-Band SAR Antenna

Progress In Electromagnetics Research Letters, Vol. 8, 105-114, 2009


A compact three-layer shared-aperture dual-band dual-polarised sub-array operating in L/C-band is designed for application in synthetic aperture radar (SAR). Square, aperture-coupled patches in the C-band and a square, perforated L-band patch are combined on the top layer. They are fed from behind the ground plane by a combined feed system. Combined layers of patches and feed layers results in a highly compact antenna suitable for low weight applications such as space borne synthetic aperture radars (SAR).
