A Literature Survey on Different MIMO Patch Antenna

This survey discusses about the different MIMO Antennas. In the current generation MIMO Antenna play an important role in the area of wireless communication. In the last decade there are many research work purposed in the area of MIMO antenna. In this review discuss on the different MIMO Antenna’s and its specification. In this survey paper also discuss about the different MIMO antenna with different parasitic elements and its effect of reduce the MIMO antenna problem such as mutual coupling and cross polarization between patch array. For the analysis of mutual coupling also focus on the surface current analysis, in this survey shows the surface current analysis of different previous work. ECC and efficiency of the MIMO antenna also play vital role to analyze the performance of the MIMO antenna. Most of the MIMO antenna suffer from Mutual Coupling (MC), low gain, lower bandwidth and Voltage Standing Wave Ratio (VSWR). These are the major problem in this survey paper. The last section discusses about the comparative analysis of last decade MIMO antenna which is presented by different researchers and compare the performance of those antenna on the basis of different result parameters such ECC, efficiency (η), surface current analysis, return loss analysis and impudence matching.
