Abstract
A phase shifter includes upper and lower conductive plates, and a dielectric strip sandwiched between the conductive plates, and a plurality of slots formed in the upper conductive plate, thereby forming a dielectric line. A rotator is positioned at either side of the dielectric strip so that the distance from the rotator to the dielectric strip varies as the rotator rotates. As the rotator rotates, the phase constant of the dielectric line progressively changes in the direction of electromagnetic propagation. The rotation of the rotator causes a change in feed phase with respect to the slots as the rotator rotates, thereby performing beam scanning.
