A Low-Profile Dual-Band Filtering Hybrid Antenna With Broadside Radiation Based on Patch and SIW Resonators

This paper presents a differentially fed dual-band hybrid antenna with broadside radiation, enhanced bandwidth, and high selectivity. The proposed antenna is constructed using a single- layer substrate based on rectangular patch resonator and substrate integrated waveguide (SIW) cavity. Herein, TM&l...
