| Abstract: | In this paper, the operating principle and basic characteristics of a low-cost ferroelectric-lens phase-scanning antenna are briefly introduced. A ferroelectric-loaded waveguide phase shifter is analyzed using finite element method. Some calculating results of the phase shifter are given. In addition, several noteworthy problems in the design are discussed taking an example of a 4-stage impedance-matched ferroelectric phase shifter. |
