Abstract

This communication proposes a curved array split into two subarrays to improve the pattern null depth and width for controlled reception pattern antenna (CRPA) systems. The proposed array consists of a single reference element at the center and two subarrays that are arranged on a spherical coverture. To consider both signal processing and electromagnetic (EM) perspectives, array patterns are calculated by using a microstrip patch antenna in conjunction with a constraint least-mean-square (LMS) algorithm. The proposed array shows significant improvement in the pattern null depth and width compared to a uniformly distributed circular array.
