A Pattern Synthesis based on Adaptive Array Theory Including Mutual Coupling

Abstract

The mutual coupling between antenna elements usually contributes a significant effect to the performance of adaptive array, especially when the interelement spacing is small. In this paper, we discuss the edge effects on a pattern synthesis based on an adaptive array theory. To diminish the edge effect of adaptive array, we simulate the reduction of mutual coupling by adding shorted parasitic elements. We can compensate the edge effects by adding shorted parasitic elements. The algorithm can be used on a large class of design problems.
