Abstract

We introduce a new application of the genetic algorithm for design of the coaxial fed circularly polarized rectangular microstrip antenna. The GA shows excellent results for the design of the microstrip antenna which have a very complex objective function including the input impedance, the effective loss tangent and the axial ratio. The objective function is derived from the cavity model, and the size and the feeding point are optimized by the genetic algorithm. The experimental results show good agreement with the simulated results.

유전자 앨거리즘을 이용하여 동축선 급전 원형 편파 사각 마이크로스트립 안테나를 설계하였다. 임피던스 및 유효 손실 탄젠트 그리고 축비 등을 포함하는 복잡한 목적 함수를 갖는 마이크로스트립 안테나 설계에 유전자 앨거리즘이 효과적임을 보였다. 패버티 마들로부터 입력 임피던스와 원형 편파의 축비를 유도하고, 안테나의 폭과 길이와 동축선 급전점을 유전자 앨거리즘을 이용하여 최적화 하였다. 설계된 안테나를 제작하고 시뮬레이션 결과와 비교하여 타당성을 검증하였다.
