    Abstract

    This paper presents a framework for the thermal noise analysis of mutually-coupled antennae in the multi-antenna system. The electromagnetic coupling for thermal noise is included in the analysis of the multiantenna system with small antenna element spacings. The method for thermal noise power calculation for the multiantenna system with coupled antennae is presented. The thermal noise behavior in the multi-antenna system is determined by applying the Nyquist's thermal noise theorem. The partial correlation of thermal noise for antenna spacing lower then a wavelength is confirmed. The signal-to-noise ratio (SNR) for the closely spaced antennae in the multiantenna system is then estimated, using presented method for thermal noise analysis. Simulation results confirm that as the antenna spacing decreases to zero, the multi-antenna system starts to act like a single antenna system.
