High-order modes in high permittivity cylindrical dielectric resonator antenna excited by a wide microstrip line

摘要

The aim of the paper is to identify the modes that can be excited by a wide microstrip line, in a cylindrical DRA situated symmetrically above it, to study the radiating performances of these modes and to present their radiating patterns. We managed to identify thirteen high-order modes; among these modes, four of them: HEM112, TMme311, TEme112, and TEme121 have high transmission performances.
