Title:
MULTI-BAND BASE STATION ANTENNA USING SELECTIVE SHIELDING SURFACE
Document Type and Number:
WIPO Patent Application WO/2023/113192
Kind Code:
A1
Abstract:
Disclosed is a multi-band base station antenna using a selective shielding surface. The disclosed antenna comprises: a selective shielding surface which passes signals in a preset frequency band; a plurality of low-band radiators located on the selective shielding surface; a reflection plate disposed below the selective shielding surface and spaced apart from the selective shielding surface; and a plurality of high-band radiators coupled onto the reflection plate, wherein the selective shielding surface has a pass band configured to pass signals emitted from the high-band radiators and block signals emitted from the low-band radiators. According to the disclosed antenna, in a multi-band base station antenna for 5G where beamforming is performed at various angles, there is an advantage in that interference between the high-band radiators and the low-band radiators can be effectively suppressed by using the selective shielding surface.
