摘要
We present a novel broadband circularly polarized(CP)antenna with filtering effect for X-and Kuband 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.
