FDTD method, U-slot patch antenna, return loss, radiation patterns.


The finite-difference time domain (FDTD) method is successfully used to analyze characteristics of a U-slot patch antenna without using commercial software packages such as HFSS, IE3D, and CST. The method is proved to be an efficiency tool for deep insight studies on complicated patch antennas. Numerical results of return loss and radiation pattern are presented. FDTD results are also compared with measurement data and shown to be in good agreement.
