A new compact square microstrip patch antenna is proposed using the optimization approach, namely, the genetic algorithm (GA). The antenna is designed at three different frequencies, 785 MHz., 1.57 GHz, and 2.46 GHz, for mobile communication, GPS, and Bluetooth applications, respectively. The simulations are carried out using IE3D from Zeland Software, which is based on the method of moments (MoM). The antenna consists of a probe‐fed truncated‐corner square patch with four inserted slits along the four diagonals and four angular grooves along the four edges of the patch. The proposed design has a reduced antenna size, as compared to the conventional microstrip antenna at a given operating frequency. The return loss, impedance, and axial‐ratio bandwidth are determined and compared with the conventional square‐patch antenna. © 2006 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2006.
