RECENT TREDS IN ANTENNA DEVELOPMENT FOR 5G WIRELESS NETWORK

Abstract

Fifth generation (5G) is the next major phase of mobile telecommunications standards beyond the current 4G, which will operate at millimeter-wave frequency band. The design of an efficient antenna plays a very important role in the performance of radio communications in any wireless device . 5G is considered beyond 2020 mobile communications Technologies. Improving the capacity of the networks with better coverage at a lower cost is the main objectives of 5G. The general agreement among different research groups working on the futuristic 5G technologies is a peak data rate of 10 Gb/s for static users, 1 Gb/s for
mobility users and no less than 100 Mb/s in urban areas led to the study of using advanced multiple-input multiple-output (MIMO) architecture as well as adaptive beam-forming. These antenna technologies may be among the key factors for overcoming some of the challenging propagation characteristics of mm-waves and could increase the spectrum efficiency, provide higher data rates, and adequate reasonable coverage for mobile broadband services. With the potential for higher frequencies as well as mm waves deployment, most 5G frequency bands are predicted to be in the range of 20-50GHz.: Extension of multi-user MIMO concept to hundreds of antennas at the base station is a promising solution to significantly increase user throughput and network capacity by allowing beamformed data transmission and interference management. Moving to
the mm-Wave frequencies for 5G mobile stations, requires new techniques in the design of antennas for mobile-station (MS) and base-station (BS) systems.
