MIMO Antenna Array Design with Polynomial Factorization

International Journal of Antennas and Propagation, 2013
One of the main advantages of multiple-input multiple-output (MIMO) antenna is that the degrees-of-freedom can be significantly increased by the concept of virtual antenna array, and thus the MIMO antenna array should be carefully designed to fully ...
