Decoupling Function for UWB MIMO Antenna to Enhance Bandwidth with Neutralization Line

In this paper, for the proposed UWB MIMO Antenna, spectral efficiency is combined with improved mutual coupling. Proposed UWB MIMO antenna modified with a wideband neutralization line. By using decoupling method, the UWB MIMO antenna covers the band of 36.5GHz .The provided wideband neutralization line is not important to be put on the copper ground and applied between two MIMO elements in the clearance area of antenna. Here the antenna size is 35x33mm2. MIMO antenna is applied in portable devices. The parameters like S parameter, realized gain, radiation pattern and total efficiency are compared using different simulations. The effectiveness of the applied wideband line of neutralization is authenticated by these simulations.
