BROADBAND NONHOMOGENEOUS MULTI-SEGMENTED DIELECTRIC RESONATOR ANTENNA SYSTEM

摘要

A dielectric resonator antenna system is disclosed wherein a dielectric material having a high dielectric constant is placed between a dielectric resonator antenna (DRA) and the antenna feed. Preferably the dielectric material having a high dielectric constant is either in the form of an insert within a cavity of the DRA or alternatively is in t he form of a thin layer between the feed and the DRA for enhancing coupling therebetween. It i s preferred that the high dielectric constant material be at least twice the value of th e dielectric resonator antenna. 14
