  • The small spacing between the double circular polarized antennas installed in the small mobile terminal can lead to the strong spatial correlation, which will directly diminish the channel capacity. From the theoretical point, this paper studies the relationship between the spatial correlation and the parameters which include the reconfigurable antenna parameters (such as the polarization rotating direction, the polarization axial ratio) and environment parameters (such as the channel cross polarization discrimination, the arrival angle). This paper also studies how to decrease the spatial correlation by adjusting the above parameters. Based on the analysis and simulation results, the design method of adaptive reconfiguration antenna is presented. The design method proposed in the paper can be used as reference for the design of reconfigurable polarization antenna in the small MIMO mobile terminal.
