Abstract

Abstract: This paper investigates an efficient procedure integrating the genetic algorithm with the method of moment for the optimal design of the smart antenna element. Then a novel coaxial collinear printed dipole antenna is presented, which is used as an element in the circular smart antenna array. The analysis of the circular smart antenna array considering the effects of mutual coupling is obtained. Finally the effectivness of the analysis is evaluated by experimental antenna arrays. The results are useful for the development of a smart antenna system in the 3rd generation mobile communications.

Key words: mutual coupling, coaxial collinear, beam-forming, method of moment
