It is part of the millimeter wave spectrum, which is a range of frequencies between 30 GHz and 300 GHz. This study proposes and investigates the 28 GHz 5G networks. A modified single element patch antenna with three grooved U-shaped holes is shown and is used to indicate a high gain and Efficiency for 28 GHz 5G antenna. The proposed antenna consists of the radiation element on a RTRogers 5880 laminate and is actuated by a microstrip feedline. The proposed work includes the most desirable characteristics, such as small size, light weight, low-cost fabrication and wide operation up to 1.4 GHz (27.1 - 28.5 GHz). The proposed antenna design also offers a high efficiency up to 89.73 %, high gain up to 8.14 dBi, and return loss up to -30 dB, resulting in attractive performance. The results obtained show that the antenna is a viable candidate for 5G applications at 28 GHz. © 2023 IEEE.eninfo:eu-repo/semantics/closedAccess28GHz5G applicationsTriple U-shaped slot High Gain and EfficiencyConference Object10.1109/ICCIT58132.2023.102739362-s2.0-85175457916576N/A573
