Evaluation of multiple antenna configurations

In this paper an analytical framework for the calculation of transmission between multiple antennas is developed. The method allows a examination of different array configurations with respect to their physical antenna properties. As an application, the ergodic channel capacities for some distinct array antenna arrangements are evaluated. This paper is organized as follows: First the ergodic channel capacity is introduced and the problem of channel normalizaton with subject to a constant transmit power constraint is illustrated. In the next section, a description of transmit and receive arrays is presented, which is based on scattering matrices and antenna theory. This description is transfered to a system-level formulation of the signal transmission between antenna arrays. In section IV, the formulation is implemented using a path-based propagation model for the intrinsic radio channel and the application of the framework is demonstrated for dual polarized antennas and linear dipole-arrays.
