Abstract :
The spatial correlation between two circular polarized antennas installed in a small mobile terminal influences directly on channel capacity. From the perspective of theory, this paper studies the relation between spatial correlation and antenna parameters (such as polarization axial ratio) & environment parameters (including channel cross polarization discrimination and arrival angle). According to the relationship between spatial correlation and channel capacity, the further research is done about how to adaptively increase channel capacity by adjusting the axial ratio of polarized antenna in varying environment.
