Abstract

In this article, a printed U‐type ultra wide‐band (UWB) antenna is designed for UWB communication using a microgenetic algorithm (MGA) in conjunction with the finite‐difference time‐domain (FDTD) method. A stepped microstrip configuration which improves the impedance bandwidth is optimized by using MGA and FDTD to achieve the UWB characteristics. The measured VSWR of the antenna is less than 2 from 3.1 GHz to 10.6 GHz. The proposed antenna has a good radiation characteristic by measurement and the simulated gain is between 3.3 and 6 dB. © 2008 Wiley Periodicals, Inc.
