Abstract

In this article, the measurement results of the dielectric resonator antenna with high‐permittivity have been presented. With this technique, a 5.4% bandwidth (return loss < −10 dB) of center frequency at about 3.5 GHz for application in WiMAX has successfully been achieved. The copolarization radiation is strongest at θ ≅ 5° from the broadside in the E‐plane. The cross‐polarized patterns are about 10 dB less than the copolarized patters in the broadside direction. The antenna has a 3 dB beam angle of about 80°. Peak antenna gain is about 5.96 dBi, with gain variations less than 1.0 dBi for frequencies within in the −10 dB S~11~ bandwidth. © 2009 Wiley Periodicals, Inc.
