MULTIBAND DUAL POLARIZED ADJUSTABLE BEAMTILT BASE STATION ANTENNA

摘要

A method and apparatus are provided for constructing a multi-band antenna (10). The method includes the steps of providing a plurality of combination-type dipole assemblies (114, 116, 118, 120, 122, Fig. 7) each defined by a box-type dipole array (36) disposed coaxially within a circular-type dipole array (134), disposing the plurality of combination-type dipole assemblies along a substantially straight line (34) over a ground plane (140) and disposing a plurality of crossed-type dipole antenna arrays along the substantially straight line in alternating order with the plurality of combination-type dipole assemblies.
