Abstract: This article presents a novel broadband circularly polarized (CP) antenna with filtering effect for X-band and Ku-band satellite wireless communication. The structure comprises a driven layer (also a filtering layer) and a stacked layer (also a CP layer). The bandpass filtering response consists of two radiation nulls, which is the combined effect of a substrate integrated waveguide (SIW) cavity-backed aperture and embedded driven patch. The chamfered patch is introduced as the stacked component with the ability to achieve CP and widen the operating bandwidth. A prototype with compact size of 0.8 is fabricated using a multilayer PCB process for demonstration. Experimental results are in good agreement with the simulated results, and show that the measured −10-dB impedance bandwidth and 3-dB axial ratio (AR) bandwidth are 10.83% and 15.54%, respectively. In addition, a peak gainLHCP of 8.9 dBic, an average in-band gainLHCP > 7 dBic, and good frequency selectivity are obtained.
