Title:
MULTIBAND BASE STATION ANTENNA HAVING IMPROVED BEAMWIDTH
Document Type and Number:
WIPO Patent Application WO/2023/121430
Kind Code:
A1
Abstract:
A multiband base station antenna having improved beamwidth is disclosed. The disclosed antenna comprises: a reflective plate; a plurality of first low-band radiators arranged on the reflective plate along a first column; a plurality of second low-band radiators arranged on the reflective plate along a second column, which is parallel to the first column and is spaced from the first column; a plurality of high-band radiators arranged on the reflective plate; and a plurality of vertical choke members arranged, between the first column and the second column, in the direction parallel to that of the first column and the second column, wherein the vertical choke members comprise a first substrate, a meander line is formed on the first substrate, and a metal line is formed under the first substrate. According to the disclosed antenna, beamwidth distortion of each radiator, caused by interference between the radiators, can be prevented, and proper isolation characteristics between the radiators can be ensured.
