Array of spatial power combination for wide angle sector coverage

Abstract

This study investigates the feasibility of using spatial power combination in small‐scale array applications that require sector coverage. A patch antenna array is used to verify the concept. The simulated result of the proposed array shows that the −6 dB angle coverage is 132° from 24° to 156° in elevation plane and the −10 dB return loss bandwidth is 4.6%. The optimized measured result indicates that the −6 dB angle coverage is 134° from 20° to 154° in elevation plane. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2990–2993, 2014
