High Gain and Efficiency Triple U-shaped Slots Microstrip Patch Antenna for 5G Applications

The 28 GHz band is a frequency band that has been allocated for use in 5G mobile communication networks. 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.
