This paper is the result of theoretical analysis and experiment of multi-polarization circular waveguide phased array antenna without matching structure. In this paper, a theoretical method for analyzing uniform and infinite planar phased array antennas is introduced. The validity of the numerical results is discussed. The convergence test results are mainly introduced. The calculation results are systematically analyzed, and the polarization characteristics of the multipolar circular waveguide array are emphatically discussed. The relations between polarization characteristics, impedance characteristics and cross-polarization components are clearly recognized. Simulator experimental results and calculation results are more consistent, the results show that the calculation is effective.
