Abstract: In this paper，the impedance matching problem of the circular waveguide latching ferrite variable polarizer has been studied，a method of calculating the impedance matching of the circular waveguide latching ferrite variable polarizer has been presented．Formulas for calculating the /4 impedance matching are given．According to the size obtained by the calculation，a device for impedance matching was made and the VSWR of the device has been measured．The measured results agree well with the calculated results． -
