Executive Summary

A compact two element MIMO (Multiple Input Multiple Output) system is proposed using H-shape antenna with parasitic elements employing polarization diversity. The proposed MIMO system offers improved bandwidth; return loss, separation between antenna elements and isolation characteristics. The system resonates at 2.36GHz and 5.2 GHz frequencies with VSWR 2, which can be used for 4G & WiMAX applications. The simulation results of return loss, mutual coupling, correlation coefficient and gain are presented. The design is performed by using Ready-made software package Zeland-IE3D. The antennas are fabricated using thin film and photolithographic technique and measured using the Vector Network Analyzer. Good agreements were found between the simulated and measured results.
