COMPACT WIDEBAND ANTENNA FOR SMALL-CELL BASE STATION BY USING 3D PRINTER

摘要

Disclosed are a wideband antenna device for a small cell base station using a 3D printer and a method for manufacturing the same. The wideband antenna device for a small cell base station using a 3D printer comprises: a disk radiator which is located based on a dielectric substrate and is a main radiator including a hole; multiple auxiliary radiators to surround the disk radiator; multiple supports to support the auxiliary radiators; and protrusion structures which are located among the supports to generate additional oscillation. The wideband antenna device for a small cell base station using a 3D printer further comprises a feeding unit to feed an antenna through a coaxial line.
