Solution of finite antenna array by using PEPA-EPA

In this paper, one hybridized method, in which the periodic equivalence principle algorithm is combined with the equivalence principle algorithm, is proposed to solve the finite antenna array with large scale. This method based on the domain decomposition method is more efficient than full-wave methods and more accurate than asymptotical methods with periodic Green´s function. Moreover, this approach avoids multi-region iterative algorithm. The numerical results reveal the feasibility of the proposed method.
