Abstract
A feeding system for providing a power using metal patterns having 'U' shape is disclosed. A phase shifter as the feeding system includes a first substrate, a first pattern as a conductor disposed on the first substrate, a second substrate separated from the first substrate and a second pattern as a conductor disposed on the second substrate. Here, the first pattern is overlapped with the second pattern, and electrical length of overlapped part of the patterns changes in case of changing phase of an RF signal outputted from the phase shifter.
