Cross-Polarization Measuring Method for Linearly-Polarized Antenna Using Two Identical Antennas

A method of cross-polarization measurement using two identical antennas is proposed in this paper. Two identical antennas are applied as both receive and transmitting antenna, and the cross-polarization level is obtained with the transmitted signals where antennas are placed orthogonally and in parallel. Cross-polarization of both the transmitting and receiving antenna is considered in this method, and therefore, the result is accurate and credible. Two antennas with different polarization state are simulated to verify the method. The simulated cross-polarization level of a single antenna shows good consistence with the calculated results, demonstrating the feasibility and practicality of the proposed method.
