## 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 pr

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 of the ground plane. © 2004 Wiley Periodicals, Inc.

## Abstract A slot‐line‐excited equilateral‐triangular dielectric resonator antenna (DRA) of very high permittivity (ε~__r__~=82) is investigated experimentally. The triangular DRA is operated at its fundamental broadside __TM__~1, 0, −1~‐mode. An improved bandwidth of ∼5%, which is 1.7 times highe
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
