Substrate Integrated Waveguide Filtering Slot Antenna for Ka-Band Satellite Communications
Authors: ,
Abstract: This paper proposes a substrate integrated waveguide (SIW) filtering slot antenna. Based on four
SIW cavity resonators and a slot locating on the last resonator, a filtering antenna was designed, targeting the
near 20 GHz satellite communication band. Simulated in the Ansys-HFSS commercial software, it exhibits a -
10 dB impedance bandwidth of 1.5 GHz and a flat gain of 5.5 dBi in the operating frequency band. Besides, the
filtering antenna has good selectivity at passband edges and features such as compact size, low profile, and low
cost, making it suitable for Ka-band satellite ground terminals
