Title:
PHASE SHIFTER AND ANTENNA DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/071983
Kind Code:
A1
Abstract:
The present invention relates to a phase shifter and an antenna device comprising same. In particular, the present invention provides the advantage of preventing physical interference between antenna elements between adjacent columns and enabling slim manufacturing of products, by comprising: a front feed strip line which is branched and electrically connected so as to enable dual polarized beam output to a plurality of radiating element modules disposed on the front of an antenna board assembly forming a plurality of antenna sub-arrays and additional antenna sub-arrays; a fixed substrate unit which is disposed on the front of the antenna board assembly, has a variable contact pattern that connects branch points of the front feed strip line and changes a physical transmission length to a first polarization side and a second polarization side of the radiating element modules; and a movable substrate unit which has a conductive terminal pattern that moves and makes contact with the variable contact pattern of the fixed substrate unit.
