Maximum capacity antenna design for an indoor MIMO-UWB communication system

In this paper, the synthesis of scenario-based capacity maximizing/optimal antennas for an indoor MIMO-UWB system is presented. Since the wavelength changes significantly across the whole spectrum, a solution must be found in order to utilize the same optimal antenna configuration for the whole UWB band. A systematic framework is presented here whereby the optimal outcome with orthogonal channels is guaranteed. The synthesis also aids in reducing the number of antenna elements needed contrary to the traditional antenna array used in MIMO systems. The resulting optimal radiation pattern and its capacity analysis are also shown.
