Abstract—In this paper, a design of ultra-wideband microstrip array antenna using a stepped line cut and U-slot combination for 5G millimeter-wave applications is proposed. The feeding technique used in the proposed design is a proximity coupling technique to improve bandwidth performance. The proposed antenna bandwidth performance is compared with the conventional antenna array design to determine the bandwidth increase. Numerical and simulation results show a significant increase in bandwidth performance compared to conventional design. The proposed antenna design can operate at frequency band 28 GHz with a bandwidth 4.47 GHz and gain 8.71dB. These results prove that the proposed antenna design can be used for 5G technology applications in the millimeter-wave band.
