Reduction of Mutual Coupling for UWB MIMO Antenna with a Broadband Balance T-Line

Abstract

A broadband balance Ttype line is proposed to decrease the Mutual coupling of a smaller ultra-wide band (UWB) multiple-performance Multiple-Input-Multiple-Output receiving antenna. With the decoupling technique presented in this research, the UWB MIMO receiving antenna described covers the 3.1 – 9.4 GHz band with a decoupling of more than 17 dBs. The proposed broadband balance T-line is actually set in the margin area between two MIMO components and can be placed on the copper ground. A margin (radio antenna range) of 20*10 mm2 is achieved. The UWB MIMO receiving antenna is simulated and SParameters, radiation patterns are found to add productivity.
