Design and Analysis of an Antenna Using Metamaterial Reflectors with Double Substrate for 5G and Satellite Communication.

Abstract

This article outlined the requirements for 5G and satellite communications antennas, including their usable range and design characteristics. An antenna that can work in several bands is preferable in order to reduce the size of a device. An antenna using a ring slotted rectangular metamaterial reflector with a double substrate for 5G New Radio (NR) applications, WIMAX, satellite and mm-Wave applications is presented in this study. The triple-band characteristic of the antenna is achieved by loading the designed rectangular metamaterial reflector. The rectangular reflector in the antenna consists of a ring slot placed in the top substrate of the antenna, contributing to triple band characteristics and enhanced performance. Furthermore, To effectively enhance the antenna's performance, two layer substrates are suggested and implemented. The presented metamaterial-inspired triple-band antenna using a double substrate has a compact size of 59.3×47.3×3mm3 and a simple structure that is easy to use. The antenna simulation results show three distinct frequencies of 4.78 GHz, 5.5 GHz, and 10.78 GHz, which cover 5G NR services applications (4400 GHz to 5000 GHz), the WiMAX band (5.25–5.85 GHz),C band (4-8 GHz), X band (8 GHz to 12 GHz). Besides, the proposed higher GHz antenna has a high gain of 13.21 dBi at the resonance frequency of 30 GHz, with an efficiency of 91.7 The suggested design provides a spectrum large enough for interference-free transmission. It can be a good use for the mm Wave application. Each band's center frequency has a reflection coefficient less than -10 dB and a peak gain greater than 7 dBi. Thus, the presented antennas have broad prospects in many wireless communication applications, like public safety applications, WLANs, satellite communication, and mm Wave application.
