A design of a single element switched beam antenna on Mushroom-like EBG structures

Abstract

This paper proposes the low profile switched beam antenna that uses only a single element for 5G applications. The antenna is placed on mushroom-like EBG structures to suppress surface waves. Therefore, bandwidth and directive gain of the proposed antenna can be enhanced. To increase signal in the desired direction and reduce interference in undesired directions, switched beam technique is proposed. There are two directions of main beam antenna 0°/180° and 90°/270° by shorted circuit at terminal edges. The results in terms of bandwidth and gain are compared when the antenna is with and without EBG. The results confirm that the bandwidth and gain can be enhanced when the proposed switched beam antenna is placed on mushroom-like EBG. © 2021 Wydawnictwo SIGMA-NOT. All rights reserved.
