摘要

In this study, the bandwidth of the rectangular microstrip antenna is improved by using a new integrated technique consisting of a novel hybrid optimization algorithm (HOA) and HyperLynx (R) 3D electromagnetic platform based on the method of moments (MoM). The novel HOA is developed by integrating the powerful mutation and crossover strategies of the differential evolution algorithm with onlooker bee stage of the artificial bee colony algorithm. The main objective of the design is to enhance bandwidth of the rectangular microstrip antenna by the etching rectangular slot on the antenna ground plane. The optimal position and sizes of the slot are determined by using the integrated optimization technique. The simulation and measurement results indicated a high improvement in the bandwidth of the rectangular microstrip antenna over 45% by using the proposed slot etching method on the ground plane. Additionally, in order to evaluate performance of the HOA, eight benchmark functions having multi or unimodal characteristics were used. The experimental results show that the performance of the HOA was better than both artificial bee colony and differential evolution algorithms.
