Description
Summary:Polarization describes the trajectory of the space electromagnetic field vector in the transmission cross section with the time changing. It reflects the regularity of electromagnetic wave vector changing over time. Three-antenna method is a kind of commonly used method which can measure antenna polarization parameters accurately. Considering the wall reflection in the anechoic chamber, the geometrical optics method is combined with three-antenna method for error analysis and correction in this paper. Measurement results and simulation results show that this method improves the measurement method of characteristic of antenna's polarization and improves the accuracy of the results.
