Estimating Combined Correlation Functions for Dipoles in Rayleigh-Fading Scenarios

While the spatial correlation function between two dipoles is well known, the angular correlation function for different arbitrary inclination angles in transmission and reception is not available in the literature. In this paper, a novel angular correlation function is proposed for two dipoles with arbitrary inclination angles between transmission and reception, which is useful for true polarization diversity schemes. Likewise, two original functions for estimating combined spatial-angular correlation are proposed. The novel functions are used with previously reported results and validated for Rayleigh-fading scenarios with isotropic scattering using a reverberation chamber.
