Title: Rotary type phase shifter
Inventor: TOMIMATSU EIJI
IPC: H01P1/17
Filed: 1982-04-06
Abstract: PURPOSE:To shift the phase with a low loss over a wide band even at a large power, by installing two phase-difference plates having equal characteristics symmetrically in the direction of input/output electric field in a circular waveguide. CONSTITUTION:In figure, 10a, 10b are phase-difference plates installed in circular waveguides 9a, 9b at an angle phi symmetrically to the axis (y), and the characteristics of them are equal entirely. The degree delta of the phase-difference plates is defined as delta degree=phase of transmission of an electric field in parallel with the phase difference plates-phase of transmission of an electric field perpendicular to the phase difference plates. As to the phase shift and loss in using the plates 10a, 10b of delta=35 deg., the phase shift is different from those of conventional plates by several degrees only, and is enough for the function and characteristics as a rotary type phase shifter, and the loss is almost negligible. Thus, the cross polarized component absorbed in resistance films 3a, 3b is minute, which causes almost no problem for the large power application.
