Abstract

In this paper, the advantages of using L‐shaped microstrip feed to excite a rectangular dielectric resonator antenna (DRA) by electromagnetic coupling are presented. This feeding technique enhances the bandwidth and gain of the antenna without affecting its size. The experimental results are validated using Fidelity software based on the finite‐difference time‐domain (FDTD) method. © 2005 Wiley Periodicals, Inc.

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
