摘要：
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 (it about 3.5 GHz for application in WiMAX has successfully been achieved. The copolarization radiation is strongest theta congruent to 5 degrees from the broadside in tire 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 frequencies within in the - 10 dB S(11) band-width. (C) 2009 Wiley Periodicals. Inc.
