## Abstract The radiation characteristics of a microstrip‐line‐excited rectangular dielectric resonator antenna (DRA) are studied experimentally. The radiation characteristics and excitation of different modes are highly influenced by the orientation of the DR, feed line parameters, and finite size

Abstract
A low‐profile equilateral‐triangular dielectric resonator antenna (DRA) of very high permittivity (ε~r~ = 82) is excited with the use of a rectangular waveguide. It is found that the present configuration has a very wide impedance bandwidth of 11.4%, which is 3.8 times of that of the previous aperture‐coupled DRA. The return loss, radiation patterns, and antenna gain of the new configuration are investigated. © 2002 Wiley Periodicals, Inc.

Characteristics of a low-profile square-disk dielectric res-( ) onator DR antenna with a ¨ery high permitti¨ity excited by a coplanar ( ) wa¨eguide CPW are experimentally studied. The CPW is open circuited by a rectangular slot which also ser¨es a coupling slot for coupling the electromagnetic energ
A broadband RMSA with a pair of rectangular slots has been proposed. Its BW is further increased either by increasing the number of pairs of slots or by using a pair of bow-tie slots. The even-mode-equivalent RMSA with a pair of slots, which is a compact RMSA with a single slot, exhibits broader BW
