Abstract :
A dual-polarized dual-band active/passive (radar/radiometer) microstrip array for remote-sensing applications is described. The measurement results meet the requirements for center-frequencies and frequency-bands, low-sidelobes (<-20 dB), good beam efficiency (>90%) and low cross-polarization (<-40 dB).
