Abstract
In communication system, the effect of mutual coupling between the closely-packed antennas often deteriorates the transmission capacity. In this paper, band-stop filters using spurline and CPS structures between two antennas are proposed to reduce the effect of the coupling. Simulation and measurement show that more than 20 dB isolation between antennas has been obtain in a 2.45 GHz MIMO system.
