Abstract :
A compact polarizer based on a corrugated waveguide of square cross-section including the input and output transitions is analysed by means of an accurate and efficient fullwave software based on mode matching, and a dual-frequency band polarizer of high electrical performance in the Ku band has been "fully" designed. The good agreement between the numerical and experimental results confirms both the design process and the proposed polarizer which can easily include different cross-sections of the attached orthomode transducer (OXIT) and horn devices, thus resulting in a very compact antenna.
