摘要
This article presents the design and implementation of a beam-steering antenna array using a 4×4 Butler matrix feed network (BMN) for 5G applications. The proposed antenna array can achieve a gain of 14 dBi and a steering range of (+16°, −47°, +46.5°, −15.7°) to cover angular range extending from 45° to 135°. To achieve that, a simple, 4 × 4 Butler matrix etched on a single-layer microstrip structure is designed, optimized, and fabricated. The proposed design incorporates phase shifters, 3-dB couplers, and cross-over couplers. The proposed matrix is employed as a feeding network for 4-element wideband LPDA antenna array. The fabrication results of the feeding matrix and antenna array show very good agreement with the simulated results. © 2023, Electromagnetics Academy. All rights reserved.
