Mutual Coupling Reduction and Bandwidth Enhancement of Microstrip Antenna using MIMO Configuration by using RIS and Polarization Diversity

Abstract

The Tremendous growth is there achieved in wireless communication in last few days. There are number of wireless systems are there present around us. Some of them are mobile communication, GPS, Wi-Fi, Bluetooth etc. and antenna is the necessary base or have central importance in any wireless systems, therefore has the importance as the heart of wireless systems. There are a number of types of antennas are available in practice and the antenna that has selected for our research is the Microstrip (MSA) , since the advantages offered by it like low cost, low weight, low profile, compact in size. Also we can very easily integrate it with microwave integrated circuit. TO increase the separation between two antenna elements the polarization diversity is used here. But the limitations of this antenna are that the low gain and narrow bandwidth. So that we are making an effort in this project to increase the bandwidth and the coverage area. Here we are achieving this in thiS project by making the suspension of the MIMO-MSA antenna. After that we the metesurface that is the reactive impedance surface(RIS) is introduced there to furtherly enhancement of the bandwidth of the antenna.The strucrure we have proposed is designed to operate over 5.725-6.4 GHz ISM band. For 4G LTE wireless communication these antennas can become a very best candidate.s
