Abstract The dual-frequency and dual-polarization microstrip antenna for space-borne SAR application is presented. The antenna uses a single aperture, and folded configuration with aired plastic film. The patch antenna has low substrate dielectric constant and wide bandwidth. The cross-polarization isolation and impedance matching are discussed. The characteristics of the space-borne SARs using this light configuration antenna are analyzed.

Key words： Microstrip antenna Single aperture dual-frequency and dnal-polarization antenna Space-borne SAR
