Abstract
The beam steering gain of E-plane notch phased array antenna is estimated using the converged active element pattern (AEP) and the directivity of an isotropic linear array. To get the gain for all scan angles, the authors first investigated the convergence of an AEP with the number of finite notch array at the center element. And then, the beam steering gain can be calculated from multiplying the converged AEP by the directivity of an isotropic linear array. To show the usability of this proposed method, a 10-element E-plane notch array antenna has been designed and fabricated. The measured AEP of E-plane notch antenna has a good agreement with the converged AEP.
