Abstract

A theoretical analysis of a symmetric T‐shaped microstrip‐fed rectangular microstrip antenna using the finite‐difference time‐domain (FDTD) method is presented in this paper. The resonant frequency, return loss, impedance bandwidth, and radiation patterns are predicted and are in good agreement with the measured results. © 2004 Wiley Periodicals, Inc.
