유전자 알고리즘을 이용한 Satellite Digital Audio Radio System Antennas 개발

The Design and Optimization of a low-profile antenna for the Satellite Digital Audio Radio System (SDARS) using a Non-Dominated Sorting Genetic Algorithm (NSGA) is presented. a fairly omni-directional elevation gain pattern over 60 degrees ＜ q ＜60 degrees are obtained. The average value of the LCP gain pattern is approximately 2 ㏈ic. The heights of the antennas are less than 0.251. The cross polarized signal level is approximately 12 ㏈ic less than the co-polarized signal level.
