Abstract
Decoupling networks (DNs) have frequently been used to obtain high isolation performance between coupled antennas in multiple-input multiple-output (MIMO) systems due to their advantage of spatial e-ciency, which is particularly important for mobile devices. However, conventional DNs sufier from narrowband limitations. In this paper, a broadband decoupling technique is proposed that broadens the isolation bandwidth using a parallel resonant point. A 1.95GHz MIMO antenna system with 460MHz of bandwidth (fractional bandwidth, FBW = 23:6%) is designed and measured using the scattering parameters. The isolation is found to be better than i15dB, while the re∞ection coe-cient is better than i6dB. Furthermore, the antenna e-ciency and envelope correlation coe-cient (ECC) are evaluated in a reverberation chamber.
