| description | Here, a planar design of a filtering antenna is presented. The design mainly comprises a semi-circular substrate integrated waveguide (SIW) cavity as a driven element and a rectangular parasitic patch with loaded metallic vias. The coax feed is used to excite the SIW cavity and the cavity excites the rectangular patch by a coupling mechanism. The loaded four metallic vias help realize the gain characteristic’s sharp selectivity with radiation null at both edges of the operating band. The simulated investigation shows that broadband response is achieved by using such a topology. The measured results show a broad band response of 7.90 % impedance bandwidth with a flat realized gain performance of 7.34 dBi in the entire operating band. The proposed design offers attractive features such as small foot prints, high gain, small cross polarization, high selectivity, and a high front-to-back ratio. |
