Diversity gain through synthesizing multiple polarizations

A novel technique for synthesizing an array of antenna elements with multiple polarization characteristics based on angular movements of a single antenna is developed. The diversity performance of the synthesized antenna array is then compared to that of a single static antenna through an extensive set of measurements based on capturing the CDMA 2000 signals (transmitted from nearby base stations) in an indoor multipath environment. The experimental evaluations which are shown to be in good agreement with theoretical predictions demonstrate significant improvement in signal detection. The measured diversity gain realized for some practical target detection requirements demonstrates the effectiveness of the proposed array synthesizing technique.
