DUAL-BAND DUAL-POLARIZED BASE STATION ANTENNA FOR MOBILE COMMUNICATION

摘要

PURPOSE: A dual band dual polarized base station antenna is provided to improve a wideband characteristic by forming a first or fourth dipole into a folded dipole structure. CONSTITUTION: A plurality of a first radiation modules are arranged on a reflector(15). The first radiation module transmits and receives two linear cross polarization for a first frequency wideband. The first radiation module includes a plurality of dipoles(10-1~10-4). A plurality of dipoles are arranged to X shape. A plurality of dipoles have a folded dipole structure. A second radiation module is interleaved between the first radiation modules.
