Bandwidth Enhancement of a Microstrip Patch Antenna for 5G Applications,

Abstract

The main disadvantage of a Microstrip Patch antenna is its narrow bandwidth. This research aims to improve the bandwidth of a microstrip patch antenna (MPA) for 5G applications. A variety of factors such as substrate element, substrate height, feeding method, and so on, which have an impact on the antenna's performance. If those parameters are chosen correctly, the 5G application requirements will be met. This work defined MPA's expanded bandwidth, which will be favorable for 5G applications. The insertion gap concept is used to extend the bandwidth of a microstrip patch antenna in this research. It would also be possible to attain a bandwidth that matches the demands and expectations of 5G applications by adjusting the size of the insertion gap. Finally, a single microstrip patch antenna operating at 28 GHz with a center frequency of 28.075 GHz has been designed. The suggested antenna's gain, bandwidth, return loss, VSWR, directivity, and efficiency are 5.83 dB, 928 MHz, - 41.282 dB, 1.017, 7.67 dBi, and 66.7 percent respectively
