Abstract
A phase shifter, more particularly relates to a phase shifter for controlling phase velocity by using stubs is disclosed. The phase shifter includes a first line configured to deliver a power into corresponding radiation elements, the first line being a conductor, and a second line configured to deliver the power into corresponding radiation elements, the second line being a conductor. Here, a first phase velocity of a first signal propagated through the first line is different from a second phase velocity of a second signal propagated through the second line.
