Embodiment Construction

[0026] An ultra-wideband dual-band cellular base station antenna and a low-band radiator for such an antenna are disclosed hereinafter. In the following description, numerous specific details are enumerated, including specific horizontal beam widths, air interface standards, dipole arm shapes and materials, and the like. However, from this disclosure, those skilled in the art will appreciate that modifications and / or substitutions may be made without departing from the scope and spirit of the invention. In other instances, specific details may be omitted without obscuring the present invention.

[0027] As used hereinafter, "low frequency band" refers to a lower frequency band, such as 698-960 MHz, and "high frequency band" refers to a higher frequency band, such as 1710-2690 MHz. A "low-band radiator" refers to a radiator for such a lower frequency band, and a "high-band radiator" refers to a radiator for such a higher frequency band. "Dual-band" throughout this disclosure ...

Abstract

An ultra-wideband dual-band cellular basestation antenna is disclosed. Ultra-wideband dual-band cellular dual-polarisation base-station antennas and low-band radiators for such antennas are disclosed. The low-band radiator comprises a dipole and an extended dipole con figured in a crossed arrangement, a capacitively coupled feed connecting the extended dipole to an antenna feed, and a pair of auxiliary radiating elements. The dipole comprises two dipole arms, each of approximately [lambda]/4, for connection to the antenna feed. The extended dipole has anti-resonant dipole arms of approximately [lambda]/2. The auxiliary radiating elements are configured in parallel at opposite ends of the extended dipole. The radiator is adapted for the frequency range of 698-960 MHz and provides a horizontal beamwidth of approximately 65 degrees. The dual-band base-station antenna comprises high-band radiators configured in at least one array and low-band radiators interspersed amongst the high-band radiators at regular intervals.

Description

[0001] Cross Reference Related Applications [0002] This application is a continuation of, and claims priority to, US Application Serial No. 61 / 730,853, the disclosure of which is incorporated herein by reference. technical field [0003] This invention relates generally to antennas for cellular systems, and more particularly to antennas for cellular base stations. Background technique [0004] Advances in wireless technology often require wireless operators to deploy new antenna equipment in their networks. On the downside, the antenna tower becomes a jumble of antennas, while installation and maintenance become more complex. Base station antennas typically cover a single narrow frequency band. Doing so has resulted in too many antennas being installed on the site. Local governments have imposed restrictions because of the visual pollution from so many antennas, making it difficult for new sites to be approved. Some antenna designs have attempted to combine the two fre...
