This paper proposes the optimum array configuration that improves the null steering performance for controlled reception pattern antenna (CRPA) systems. The proposed array is composed of a center reference element and six auxiliary elements, and its array pattern is adaptively steered to mitigate the interference effect in conjunction with a constraint least-mean-square (LMS) algorithm. Then, the null steering performance of the proposed array is compared to that of a uniform circular array
