Ultra-Wideband Steerable Antenna Array Based on EBG Structure for Millimeter Wave 5G Applications

An ultra-wideband miniature antenna array based on electromagnetic band gab (EBG) has been presented for the five generation of wireless communication (5G) applications. The proposed antenna array is fed by a 3dB hybrid coupler. Simulation results show that two beams steering toward ±13° with 7.35 dB maximum gain magnitude in E-plane at 28 GHz, are achieved. Thus, by using EBG structure, the proposed antenna array achieves an ultra-wideband (UWB) behavior, that covers 23.28-35.78 GHz (44.64%) frequency range.
