Abstract

A dual and wideband single‐element rectangular dielectric resonator antenna (DRA) excited by a microstrip aperture is investigated experimentally. It provides two passbands in the ranges of 2.21–2.855 GHz and 4.385–5.455 GHz, which are popular bands for wireless local‐area networks (WLANs). The return loss, antenna gain, and radiation patterns of the proposed configuration are measured. © 2005 Wiley Periodicals, Inc.

For the propagating mode, the field is evanescent outside the dielectric. We expect the field to be very small when it reaches the PEC boundary. The difference in higher frequency is because the mesh in SOM is not as dense as that in finite-difference method. ## 4. CONCLUSION In this paper, the wa
