Abstract
In this article, the measurement results for the use of high‐permittivity material in stacked patch antenna, with coplanar waveguide feed line at 2.5 GHz, have been presented. With this technique, a 13% bandwidth (return loss < −10 dB) of center frequency at 2.5 GHz has been successfully achieved. The copolarization radiation is strongest at θ ≅ 0° from the broadside both in the xz‐ and yz‐ planes. The antenna has a 3 dB beam angle of about 110° and 85° in the xz‐ and yz‐ planes, respectively. Peak antenna gain is about 4.9 dBi, and the gain is >2.0 dBi for frequencies within in the −10 dB S~11~ bandwidth. © 2009 Wiley Periodicals, Inc.
