The present Wireless communication systems such as 3G, Bluetooth and 4G technologies require larger data transfer rates with high speed and accuracy. The Multiple Input Multiple Output (MIMO) technology is one of the advanced wireless communication systems, which is very much capable to accomplish the demands of the present and emerging communication systems like Wi-Fi, 3G and 4G etc. Patch antennas which are low cost, low in weight, planar or conformal layout, easier to fabricate, and able to be integrated with electronic or signal processing circuitry show good compatible with MIMO systems. Patch antennas can be designed in any desired shape like ring, circular, triangular etc. Flexibility in patch antenna design makes it preferable for many modern wireless communication applications. The placement of multiple antennas in small region in a MIMO system cause mutual coupling. In this study, the physical aspects of the mutual coupling between two identical patch antennas investigated. Long Term Evolution (LTE) is a wireless broadband technology, which is designed to support roaming Internet access via cell phones and handheld devices. As LTE offers significant improvements over older cellular communication standards, for instance a 4G (fourth generation) technology along with WiMAX. In the proposed system, I have analysed dual band micro strip patch antenna and their use in MIMO communication systems. Modified Rectangular insert feed patches have demonstrated a great capability of miniaturization due to its geometrical shape. Etching some slots in the patches changes the antenna frequency response so that dual band designs are easily conceived. Several configurations are analysed using the HFSS simulation software and a 2.4 GHz & 3.8GHz two-port antenna is fabricated on a FR-4 substrate. Simulation results and some graphics are also included.
