Modified Calculation Based on Genetic Algorithm for the Resonant Frequencies of 30°-60°-90° Triangular Patch Antenna

Abstract

In this paper, a genetic algorithm based approach to the modified resonant frequency calculation for a 30°-60°-90° triangular patch antenna (TPA) on a single substrate is presented. Continuous parameter genetic algorithm (CPGA) is used to modify expressions for the resonant frequency calculation of a 30°-60°-90° TPA on a single substrate for improving the accuracy. The results obtained by CPGA for different 30°-60°-90° TPAs are compared with the experimental and the best theoretical results given in literature. It is a simple, fast and accurate approach to the computer aided design of a 30°-60°-90° TPA on a single substrate.
