MIMO CAPABILITY OF A MINIATURISED ANTENNA ARRAY WITH A DECOUPLING AND MATCHING NETWORK

摘要

We propose and evaluate an antenna array consisting of three, quarter-wavelength spaced, monopoles and a passive network. The latter decouples and matches the antenna array to prevent gain reduction. At the same time, it forms orthogonal radiation patterns, which divide the space into three different sections. By using a geometry-based channel model, the Ilm-Prop, we are able to quantify the improvement of the channel capacity and the bit error rate provided by the passive network with respect to the array without network under realistic conditions.
