Abstract

Smart antennas provide a unique and viable solution to the problem of multipath effects on signal propagation, particularly in the millimetre wave band. Multiple-Input Multiple-Output (MIMO) technology has certain advantages that can prove instrumental in not just eliminating multipath but turning it into an advantage and using it to improve communication link quality. With the use of MIMO and its unique beamforming capabilities, path loss can be significantly reduced, and more efficient use of the communications frequency spectrum can be achieved. MIMO antenna technology consists of a smart antenna array with multiple transmitting inputs and multiple receiving outputs. In this review, we compare some of the latest developments in MIMO technology. It focuses on design techniques, performance parameters, and novel developments. Recent developments include improvements in UWB, multi-band, and smart wear.
