Abstract: This thesis examines the performance of dense antenna arrays in Multi-Input Multi-Output (MIMO) systems. An N-element antenna array is regarded as an N-port network with non-vanishing off-diagonal elements in the network parameter matrices, for example, the scattering parameter matrix. A modal expansion is then used to express the matrix in terms of mutually orthogonal eigenmodes. To facilitate the simultaneous removal of signal correlation and gain reduction due to the cross-talk, an approach, which employs an RF decoupling network at the array ports, is proposed. To verify the theory, a practical design of a novel, compact, four-port, dual-polarized aperture-coupled patch array with decoupling network is presented and tested. This antenna would be attractive for WLAN applications with limited antenna platforms such as PDAs, smart phones or laptop computers, where element spacing is significantly smaller than half a wavelength.
