Abstract
A phase shifter and a method of making a phase shifter are disclosed herein. The phase shifter may include a housing, a dielectric, an electrode, and a liquid crystal layer. The housing includes first, second, third, and fourth conductive walls, each conductive wall being opposite one of the other walls. The dielectric is situated within the housing and defines a compartment within the housing. The electrode is aligned with the compartment. The liquid crystal layer fills the space of the compartment. A bias line is coupled to the electrode. The phase shifter may be integrated with as substrate integrated waveguide.
