Frequency reconfigurable ultra-wide band MIMO antenna for 4G/5G portable devices applications: Review

The rapid development in the sector of wireless communication demands for system that fulfill multifarious needs and standard requirements which are increasing day by day. Existing antennas like wire, loop, travelling wave antenna does not meet the requirements of modern-days wireless communications. Design of reconfigurable antenna enables one antenna to be used for numerous applications. This antenna can switch its characteristics in real time condition. According to industrial requirements 5G wireless communication devices should be smaller in size and provide high data rate, channel capacity, multiband operations so that it can push the development of more versatile wireless technologies compared to single antenna. Design of reconfigurable MIMO antennas is the best solution to such requirements. MIMO antenna already proved in Wi-Fi, WiMAX and LTE wireless services that it can provide high data rate throughput and avoid interference. In MIMO system multiple antennas are existing for embedding MIMO in portable devices it should be compact in size. Therefore, it is a challenging job to design UWB MIMO antennas having high isolation and compact size. This survey concentrates on many researches carried out related to frequency reconfiguration, microstrip patch and frequency tunable MIMO antenna for various wireless application. © 2020, Research Trend.
