US 7,405,710 B2 · Multiband dual polarized adjustable beamtilt base station antenna

Abstract

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.

Dependent claims

A method of constructing an antenna comprising the steps of:

providing two or more combination-type dipole assemblies each defined by an inner dipole array disposed coaxially within an outer dipole array around an array center,
each dipole in the inner array entirely disposed within an inner periphery of the outer dipole array when viewed in plan;
and
disposing the two or more combination-type dipole assemblies along a substantially straight line.
