Mutual Coupling Reduction Techniques between MIMO Antennas for UWB Applications

Abstract

The recent research has proved that the Multiple-input-multiple-output (MIMO) systems can substantially increase the channel capacity by employing multiple antennas at both the transmitter and receiver, without increasing either transmitter power or bandwidth. Hence it is very much essential to know all the aspects of MIMO system. Usually, in any MIMO system the antenna design plays a major role in improving the system performance and channel capacity. The antenna bandwidth must support the wireless system for transmitting larger data rates. Also, the mutual coupling effect between the antennas must be taken into consideration, while designing an efficient MIMO system. The objective of this paper is to discuss various techniques to reduce mutual coupling of MIMO antennas for UWB application
