Abstract
This research work is devoted to propose and investigate a new millimeter wave antenna array in the 28 GHz band for the fifth generation (5G) of the mobile communication systems. For this purpose, a modified patch antenna with double U-shaped etched slots is presented and employed to propose high gain 5G antenna array. The suggested array is composed of two radiating elements excited by a microstrip feed line and placed on the RTRogers 5880 laminate. An attractive performance is noted where the proposed array combines the most required features including the small size property, wideband operating of 2GHz (27.5-29.5 GHz), high efficiency up to 93% and high improved gain up to 12dB. The attained results proved the eligibility of the antenna to be a good contender for the 5G applications at 28GHz.
