AI Technical Summary

Problems solved by technology

This has resulted in too many antennas being installed at one site
Local governments have imposed restrictions and made approval of new sites difficult due to visual pollution from so many antennas
Some antenna designs have attempted to combine the two bands and extend the bandwidth, but due to many air-interface standards and the growth of frequency bands, many antennas are still required

Embodiment Construction

[0018] An ultra-broadband dual-band cellular base station antenna and a high-band radiator for the antenna are disclosed below. In the following description, numerous specific details are described including specific beamwidths, air interface standards, dipole antenna arm shapes and materials, and the like. From this disclosure, however, it will be apparent to those skilled in the art that modifications and / or substitutions can be made without departing from the scope and spirit of the invention. In other instances, certain details may have been omitted so as not to obscure the invention.

[0019] Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The articles "a" and "an" are used herein to refer to one or more than one (ie at least one) of the grammatical object of the article. By way of example, "a unit" means one unit or more than one unit. ...

Abstract

A high-band radiator of an ultra-wideband dual-band basestation antenna is disclosed. The high-band radiator comprises at least one dipole, a feed stalk, and a tubular body made of conductive material and having an annular flange. Each dipole comprises two dipole arms made of conductive material. The feed stalk feeds the dipole and comprises a non-conductive dielectric substrate body and conductors formed on the substrate body to function as a balun transformer. The feed stalk is connected with the dipole at one end and has at least one feed connector at the other, with the conductors coupled there-between. The tubular body is adapted for electrical connection through the annular flange to the ground plane at the open end; the body is short-circuited at the other end to define an internal cavity of the tubular body. At least a portion of the feed stalk is disposed within the tubular body.

Description

[0001] This application requires the Australian Provisional Application No. AU 2013903473 entitled "High-band Radiators In Moats For Basestation Antennas" ("High-band Radiators In Moats For Basestation Antennas") filed on September 11, 2013 priority of the patent application and is incorporated herein by reference. technical field [0002] The present invention relates generally to antennas for cellular systems, and more particularly to antennas for cellular base stations. Background technique [0003] Advances in wireless technology often require wireless operators to deploy new antenna equipment in their networks. On the downside, towers have become cluttered with multiple antennas, and installation and maintenance have become more complicated. Base station antennas typically cover a single narrow frequency band. This has resulted in too many antennas being installed at one site. Local governments have imposed restrictions and made approval of new sites difficult due to...
