Document Type and Number:
WIPO Patent Application WO/2024/033985
Kind Code:
A1
Abstract:
Provided is a phase shifter which, in order to be applied to a patch antenna of a size corresponding to the wavelength of signals to be transmitted and received, regardless of the polarization state of radio waves to be transmitted and received, comprises: a hub part that is connected to a power-feed point of the patch antenna; a switch group that includes a plurality of switches; a spoke section that includes a plurality of radial lines that are arranged radially around the hub part and are electrically connected to the hub part through any of the plurality of switches; and a rim part that includes a plurality of arcuate lines that are arranged along a circular arc centered on the hub part and are electrically connected to the plurality of radial lines through any of the plurality of switches.
