Millimeter Wave Doughnut Slot MIMO Antenna for 5G Applications

A change from a long and distant period of history of cellular communication aims in the deployment of 5G base stations and antennas. Upgrading from 4G to 5G results in three main benefits: faster speed, shorter delays and increased connectivity. Extremely fast 5G speeds means extremely high frequency, the millimeter wave frequency. Due to enhancement in technologies, mmwave can be used in most of the new electronic components mainly, antennas. This paper intent to design an antenna in millimeter wave frequency range (24GHz-300GHz) for 5G applications. A doughnut slot antenna with improved gain using MIMO configuration is presented. There exists valuable isolation at 28GHz. The dual band antenna resonates at 28GHz and 45.54GHz suiting 5G applications. The antenna is compact sized and extending to MIMO gives low values of ECC at all frequencies. Doughnut slot patch antenna is commendable for future 5G communications.
