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

摘要

PURPOSE: A dual band dual polarized antenna for a mobile communications base station is provided to facilitate the design of an antenna by appropriately controlling the number of a first and a second radiation device module and an interval. CONSTITUTION: A first and a second radiation module are arranged on a reflector. The first radiation device module receives and transmits two linear orthogonal polarizations for a first frequency band. The first radiation module includes a first or a fourth dipole(10-1~10-4). The first or the fourth dipole is arranged into an X-shaped pattern. The first and the third dipole are arranged at the angle of +45 degrees. The second and the fourth dipole are arranged at the angle of -45 degrees. The second radiation device transmits and receives two linear orthogonal polarizations for a second frequency band.
