Abstract :
The circular switched parasitic array (CSPA) is a smart antenna system promising to play an important role in mobile systems manufacturing. In this paper, an effort to optimize the overall structure of a five-element monopole CSPA above a square wire grid plate in order to form a desired radiation pattern and achieve impedance bandwidth at the V UHF band is carried out utilizing the genetic algorithms (GA) optimization technique. The resulting configuration is then compared with the same monopole array placed above a wire grid plate with skirt.
