Parallel-plate slot array antenna fed by rectangular waveguides at its lower-edge sides has been proposed. This antenna panel can be applied for dual circularly polarized deployable synthetic aperture radar (SAR) antenna onboard small satellite. As to confirm the feasibility of the antenna implementation, a development of one panel antenna system with single polarization (RHCP) has been conducted. The antenna design with simplified model by high-frequency structure simulator (HFSS) and antenna measurement results are explained in this paper. It is shown that antenna with gain and efficiency of 34.9 dBic and 54%, respectively, are achieved at the targeted center frequency (9.65 GHz).
