Design of wide-band/wide-scan E-plane notch phased array considering active element pattern

In this paper, we propose a method to estimate the gain of E-plane notch phased array. In order to get the gain for all scan angles, first we investigated the convergence of AEP (active element pattern) with the number of finite notch array at the center element where other elements are terminated. And then we got the antenna gain by multiplying the converged AEP by the directivity of isotropic element. As an example, E-plane notch phased array is designed and the beam steering gain is calculated to show the validity of the proposed method. In this work, the simulation of notch antenna is performed with the commercial time-domain solver.
