A Survey on 5g Spectrum and Design of Microstrip Antennas for 5g Wireless Networks

Abstract

The demand for high data rate, good channel capacity and reliability has always been the main area of concern in the era of modern wireless communication systems. Present days mobile communication spectrum, below 3 GHz bands is faces more shortage and not able to serve people with more device connectivity and data speed. The 5th generation mobile technology standards have the guts to deliver high data rates, low-latency communications, and massive device connectivity. For the efficient distribution of the 5G systems and in order to support higher bandwidth need to design efficient antenna at sub 6 GHz and mm wave frequencies. This article presenting, different frequency bands allocated to 5G in the range of sub-6GHz and millimeter wave frequencies in various countries and the problems in utilization of 5G mm-wave spectrum are discussed along with solutions. Review focused in view of acquiring knowledge about the tips to achieve good radiation properties. Previous researchers introduced lot of antenna design techniques like employing dielectric lens, meta-material lens, parasitic elliptical patch, array topologies, creating slits, slots, and stubs etc., to improve gain and bandwidth of antenna.   Though these kinds of techniques used in antenna design, there improvement in one antenna property is frequently accompanied by decline in its other property performances. Proposed work also gave the comparative studies on results of different micro strip antennas, designed using various techniques by previous researchers.
