Abstract

In this article, a novel method is presented to improve the coupling of dielectric resonator antenna (DRA) excited by a waveguide slot at the shorted end.A rectangular DRA is excited by a thick ground plane slot, which is fed by a capacitive waveguide junction (CWJ)‐coupled waveguide end. The objective of using a CWJ is to substantially increase the power coupling to the DRA. Measurements were carried out to verify the design, and a reasonable agreement between them is obtained.

## Abstract Novel slot‐fed dielectric resonator antenna is studied experimentally. The antenna is comprised of a rectangular dielectric resonator and a mictrostrip fed coupling slot. The multiband resonances of the two radiators i.e., slot and dielectric resonator are combined to extend the antenna

## Abstract In this paper, a dielectric resonator antenna for dual‐frequency operation is proposed. The proposed antenna is excited by dual 50Ξ© microstriplines and printed in a single metal layer, and therefore is easily constructed. In this design, the operating frequency is mainly controlled by t

A coaxial-fed hexagonal dielectric resonator antenna (HDRA) producing circular polarization is investigated experimentally. Circular polarization is achieved by exciting the orthogonal HE 11␦ modes of the HDRA in phase quadrature. The return-loss, impedance, and radiation characteristics are studied
