Phase shifter using substrate integrated waveguide

摘要

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.

1. A phase shifter using a substrate integrated waveguide (SIW), the phase shifter comprising:
a substrate; and a waveguide integrated on the substrate, wherein the waveguide comprises an input port, an output port, two columns of via walls which are separated by a width of the waveguide and are arranged parallel to each other, and a plurality of air holes which are formed to shift a phase of a signal between the input port and the output port, wherein an amount by which the phase of the signal is shifted between the input port and the output port varies according to at least one of a diameter of the plurality of air holes, a distance between adjacent air holes of the plurality of air holes, and the number of the plurality of air holes, wherein the plurality of air holes does not include surfaces with metal material.
