Patent ID: 8836608

Claim:
A method of improving the capacity and mutual coupling performance of a MIMO antenna array, comprising: selecting N T transmitter antennas and NR receiver antennas each comprising a metamaterial substrate so as to form a resonance structure based on induced inductance of the metamaterial substrates combined with the capacitance of the metamaterial substrates; determining a statistical description of a transmission environment including said MIMO antenna array, where the statistical description is provided in a matrix H i , where Hi is the normalized channel matrix corresponding to an i th channel realization where H i includes interference and signal to noise as a product of the location and spacing of the N T transmitter antennas and N R receiver antennas; using the normalized channel matrix to compute the channel capacity C for each array configuration for a given subcarrier; and placing said N T transmitter antennas and said N R receiver antennas, mounted on said metamaterial substrates, in an array configuration so that the resulting antenna array has channel capacities C that are approximately the same as channel capacities C of relatively larger antenna arrays formed without said metamaterial substrates.
