Design of a dual-band 12-element mimo antenna array for 5g mobile applications

Abstract

This article presents a dual-band 12-element antenna system based on slot antennas for fifth-generation (5G) of mobile communication. The basic structure of each antenna element is composed of a T-shaped slot. The antenna array is designed to operate at LTE 42 and LTE 43 bands ranging from 3400–3600 MHz and 3600–3800 MHz, respectively. The impact on the antenna parameters due to the user’s hand is also explored. The isolation between antenna elements is better than 14.8 dB with a total efficiency of more than 74%. A small envelope correlation coefficient less than 0.05 and the channel capacity of 61.9 bps/Hz make the proposed array a viable solution for 5G smartphones.
