Abstract

This work presents a compact, switched-beam array antenna on 4 × 4 Butler Matrix (BM) beamforming network (BFN) at 28 GHz for fifth generation (5G) wireless system. A single layer has been chosen to ensure low cost and ease fabrication. The four input ports of the designed antenna have the capability of producing four independent directional beam patterns at 13.8°, -43.5°, 44° and -14°, when P1, P2, P3 and P4, respectively are excited. The radiation efficiency obtained from each of the four ports is well above 80% at the designated frequency. The peak antenna gain of 15.9 dBi is obtained at port 1 and 4. The design is verified by measurement and all results have a good correlation with simulation.
