摘要

The new generation 5G technology is being investigated to replace the existing 4G and long-term evolution (LTE) communication system. Different countries are considering various bands of frequencies to utilize for 5G frequency spectrum. In India, new radio (NR) bands are being considered for 5G applications. In these bands, several antennas are being implemented for n77 or n78 bands. Here, n77 operates at 3700 MHz with bandwidth covering from 3300 to 4200 MHz; similarly, n78 operates at 3500 MHz with bandwidth covering from 3300 to 3800 MHz. In this work, we propose a meta-surface-inspired antenna for 5G applications. The design consists of an “E”-shaped patch, closely placed with a “π”-shaped patch substrate to form the radiator. The patch substrate only contains radiator at top and no copper cladding at back side. The second substrate contains plane ground at top side with a unique shaped slot made at center. The backside of the second substrate contains feed network or feed structure. The antenna aimed to be compact inside to serve either n77 or n78.
