Design of C-band Dual-polarized waveguide slot Antenna for Spaceborne SAR
In this paper, a C-band dual-polarized waveguide slot antenna used in satellite synthetic aperture radar (SAR) subsystem is introduced. Horizontal polarization and vertical polarization realized by different slot forms respectively. The dual polarization waveguide slot antenna is composed of two layers of cavity. The vertically polarized waveguide ridge with capacitance plates reduces the performance with ridge gap. The final design structure is simple and easy to fabricate, Based on the project requirements, a 16*16 array is fabricated. the experimental results achive excellent performance. The VSWR is less than 1.6, the efficiency is more than 90%, the cross polarization is lower than -35dB.
