Abstract

A circularly polarized silicon integrated W-band direct detection receiver (DDR) for use in six-port polarimetric radar systems has been designed, numerically optimized and fabricated. The major advantage of the receiver is a novel low-loss, purely planar dual patch antenna (DPA) layout, which allows the receiver to be manufactured using monolithic integration. The measurement results for the receiver demonstrate a good cross polarization discrimination (XPD)>14 dB@76 GHz over a wide range of the scan angle (12 dB@/spl plusmn/20/spl deg/).
