Title:
DUAL-POLARIZED BASE STATION ANTENNA RADIATOR
Document Type and Number:
WIPO Patent Application WO/2020/214015
Kind Code:
A1
Abstract:
A dual-polarized base station antenna radiator is provided. The disclosed base station antenna radiator comprises: a first substrate placed perpendicularly to a reflector plate, a feeding line being formed on the upper surface of the first substrate, and a first metal pattern and a second metal pattern being formed on the lower surface thereof in "ㄷ" shapes or "C" shapes; a second substrate placed perpendicularly to the reflector plate and perpendicularly to the first substrate, a feeding line being formed on the upper surface of the second substrate, and a first metal pattern and a second metal pattern being formed on the lower surface thereof in "ㄷ" shapes or "C" shapes; and a third substrate coupled to the first substrate and the second substrate placed perpendicularly to each other, the third substrate being positioned parallel to the reflector plate, and a radiation patch being formed on the upper surface of the third substrate. The first metal patterns of the first substrate and the second substrate are electrically connected to the radiation patch through holes formed in the third substrate. The first metal patterns and the second metal patterns have openings formed in opposite directions and disposed to be spaced apart from each other. The feeding line provides a feeding signal to the second metal patterns through via-holes. The disclosed base station antenna radiator may provide stable polarization characteristics with regard to frequencies.
