A Review Of Various Isolation Techniques For MIMO Antenna

Various four-element multi-input multi-output (MIMO) antennas suggested and designed by numerous authors over the last decade are covered in this review of the literature. In the present scenario, the MIMO antenna is an essential part of wireless communication. Over one decade a number of researchers worked on the MIMO antenna for different applications. This review presents some recent novel work on MIMO antenna with different specifications and configurations. This review surveys the different MIMO antenna research work with different parasitic elements like different isolation techniques used. In this survey, mutual coupling is also emphasized. The extent to which a MIMO antenna works are the Envelope Correlation Coefficient (ECC), diversity gain, return loss, Channel Capacity Loss (CCL), and efficiency. This survey's last section compares the implementation of various MIMO antenna with and without the inclusion of any extra decoupling structures or techniques.
