Implementation of a correcting coupling mechanism to mitigate surface wave in phased arrays

Abstract : This paper presents a solution to extend the scanning range of a phased patch array whose scanning performances are limited by surface wave coupling. Two main aspects are investigated. The first section is a thorough description of the coupling mechanism occurring in the reported array. The second section introduces a revised array topology that extends the scanning range. The proposed solution is based on the introduction of an additional coupling mechanism within the structure. Its goal is to compensate the harmful effect of the surface wave, and it is implemented by means of additional microstrip lines connecting the array sources. © 2018 Institution of Engineering and Technology.All Rights Reserved.
