Abstract
A novel dual-band square microstrip patch antenna for bandwidth improvement and antenna size reduction in a single design is proposed. It can operate at dual frequencies of 1.7 GHz and 5.5 GHz. The fundamental parameters of the antenna such as bandwidth, return loss, gain, radiation pattern, and polarization are obtained. This square piece patch antenna has less return loss of −40 dB with bandwidth of 40 MHz and 200 MHz in two bands, respectively. The sensitivity of patch antenna towards its patch shape is also discussed. Simulation tool, based on the method of moments (ZELAND IE3D version 12.0) has been used to analyze and optimize the antenna. © 2010 Wiley Periodicals, Inc.
