Abstract
A dielectric phase shifter comprises a cavity having an elongated receiving space, a phase shifting circuit disposed inside the receiving space, and a dielectric element slidably mounted in the receiving space and parallel with the phase shifting circuit. A rail is disposed on an inner wall of the cavity for preventing contact between the movable dielectric element and the phase shifting circuit. By providing a number of rails between the phase shifting circuit and the dielectric element, direct contact between the dielectric element and a feeding network is prevented. As a result, no additional force will be imposed on the feeding network and reliability is enhanced. Moreover, wear of the feeding network and/or dielectric element during operation of the phase shifter is eliminated.
