Antenna Selection for MIMO Systems with Closely Spaced Antennas
EURASIP Journal on Wireless Communications and Networking, 2009 Physical size limitations in user equipment may force multiple antennas to be spaced closely, and this generates a considerable amount of mutual coupling between antenna elements whose effect cannot be neglected. Thus, the design and deployment of antenna selection schemes appropriate for next generation wireless standards such as 3GPP long term ...
