Design of a Compact Omnidirectional Leaky-Wave Antenna Fed by Higher Order Mode
IEEE Transactions on Antennas and Propagation(2022)
Abstract
This article presents a novel leaky-wave antenna (LWA) based on a dielectric-filled rectangular waveguide (RWG) and fed by a higher order mode. The proposed quasi-uniform LWA has a compact configuration that is suitable for microwave applications, featuring the omnidirectional radiation patterns and low cross-polarization. In the frequency band of interest, the higher order mode, i.e., the TM...
