Abstract :
A new method to measure the four-port scattering matrix of a dual-polarization antenna is proposed. A two-port vector network analyzer is connected to the two excitation ports of the antenna to measure its 2/spl times/2 scattering matrix. The formulation is developed to solve the four-port scattering matrix of the dual polarization antenna from the measured two-port scattering matrix with two calibration scattering objects.
