Development of Low-Profile Filtering Antennas With Dual-Mode Cavities
Two filtering antennas implemented on the dual-mode cavities are proposed, investigated and experimentally verified in this paper.They are developed based on the single-layer substrate integrated waveguide (SIW) technology.The rectangular SIW dual-mode cavities (using TE102, TE201 and TE301 modes) are effectively stimulated with a simple capacitive
