Title:
FULL ANALOG PHASE SHIFTER AND ANTENNA APPARATUS INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/128683
Kind Code:
A1
Abstract:
The present invention relates to a full analog phase shifter and an antenna apparatus including same, and more particularly, comprises: a variable switch panel including a first conductive pattern terminal and a second conductive pattern terminal; and an antenna element substrate on which a plurality of array antenna elements are arranged and a transmission line being in contact with the first conductive pattern terminal and the second conductive pattern terminal is pattern-printed, wherein, due to a phase shift caused by contact points of the transmission line with respect to the first conductive pattern terminal and the second conductive pattern terminal, phases of the plurality of array antenna elements are linearly distributed on a same reference phase plane, thereby providing an advantage of easily implementing a mirror symmetry structure having a linear phase distribution only by a phase shift in an RF stage without phase conversion in a digital stage.
