Abstract

An antenna based on a three‐dimensional metallic photonic bandgap (MPBG) structure consisting of many parallel metallic short wires is considered. An explicit method is introduced to calculate the radiation pattern for such an antenna system. The explicit method is verified numerically by comparing the results obtained by the finite‐difference time‐domain method. The present method improves the computation speed significantly. A genetic algorithm is used to make an optimal design for such a 3‐D MPBG structure‐based antenna. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 376–381, 2001.
