Abstract
Provided is a phase shifter using a substrate integrated waveguide (SIW). The phase shifter includes: a substrate; and a waveguide integrated on the substrate, wherein the waveguide includes an input port, an out port, two columns of via walls which are separated by a width of the waveguide and are arranged parallel to each other, and either a plurality of air holes which are formed to shift a phase of a signal between the input port and the output port or a plurality of rods, each including an air hole and a dielectric material inserted into the air hole.
