Design and Parametric Analysis of the Dual Mode Ferrite Phase Shifter with Linear Polarization

The design of a dual mode ferrite phase shifter with linear polarization is investigated in this paper. Phase shifters are one of the most commonly used components in phased array radars. The main parts of this phase shifter are ferrite rod, yoke and polarizer. The main specifications of phase shifter are 10.1-10.7 GHz bandwith, less than 1 dB average loss and 360 degree phase shift. Due to the limitations of manufacturing in some parts, a parametric analysis has been performed on some specifications and the allowable amount of changes in these parameters such as yoke and ferrite rod contact length and the air gap between them, the length and radius curvature of polarizer has been reported.
