Abstract

A novel evolutionary algorithm for broadband patch antenna design is presented. The differential evolution algorithm (DE) and the method of moments (MOM) are combined to achieve the optimum antenna satisfying a certain design criterion. The antenna geometric parameters are extracted to be optimized by DE, and a fitness function is evaluated by MOM simulations to represent the performance of each candidate design. A broadband patch antenna is designed using the optimizer. The optimized patch antenna is fabricated and measured to validate the robustness of the algorithm. The measured 38.6% bandwidth exhibits the prospect of the DE/MOM algorithm in practical patch antenna design. Β© 2009 Wiley Periodicals, Inc.

## Abstract In this article, a C‐Band broadband patch antenna is designed. The binary particle swarm optimization (BPSO) combining with IE3D software is adopted to broaden the bandwidth of the patch antenna automatically. Characteristics of the antenna are calculated using the well‐known Zeland IE3

Collected f 0 results are shown in Figure 15. The center frequency varies with s/(s Ο© w g ) ratio around the theoretical value c 0 /(4h g ) Ο­ 1 GHz. However, it is noted that as the period length decreases (that is, (s Ο© w g )/ G decreases), f 0 depends less on the s/(s Ο© w g ) ratio. The dependence
