| Abstract: | A new methodology for measuring the characteristic parameter of the circular polarization antenna using the linear polarization antenna is proposed. The mathematical model of the measurement method is founded based on the decomposition theory of the ellipse polarization microwave. It is easy to obtain the characteristic information on the circular polarization antenna, such as pattern, axial ratio, gain, etc., through the use of two orthogonal measures with a linear polarization antenna, and also a practical testing system is developed. By measuring the circular polarization antenna practically, this method has been proved to be of merits of effectiveness, high automatization, and high measurement accuracy. |
