Low-band radiators of an ultra-wideband dual-band dual-polarization cellular basestation antenna and ultra-wideband dual-band dual-polarization cellular base-station antennas are provided. The dual bands comprise low and high bands. The low-band radiator comprises a dipole comprising two dipole arms adapted for the low band and for connection to an antenna feed. At least one dipole arm of the dipole comprises at least two dipole segments and at least one radiofrequency choke. The choke is disposed between the dipole segments. Each choke provides an open circuit or a high impedance separating adjacent dipole segments to minimize induced high band currents in the low-band radiator and consequent disturbance to the high band pattern. The choke is resonant at or near the frequencies of the high band.

Dual-band interspersed cellular basestation antennas

A radiating element for a base station antenna includes a feed stalk and a cross-dipole radiator mounted thereon. The cross-dipole radiator includes a dielectric mounting substrate, a first metal dipole that extends along a first axis on the dielectric mounting substrate, a second metal dipole that extends along a second axis on the dielectric mounting substrate that is generally perpendicular to the first axis, and an adhesive layer between the dielectric mounting substrate and the first and second metal dipoles.

Base station antennas having radiating elements with sheet metal-on dielectric dipole radiators and related radiating elements

A multiband antenna, having a reflector, and a first array of first radiating elements having a first operational frequency band, the first radiating elements being a plurality of dipole arms, each dipole arm including a plurality of conductive segments coupled in series by a plurality of inductive elements; and a second array of second radiating elements having a second operational frequency band, wherein the plurality of conductive segments each have a length less than one-half wavelength at the second operational frequency band.

Cloaked low band elements for multiband radiating arrays

A dual-polarized radiating element for a base station antenna includes a first dipole that extends along a first axis, the first dipole including a first dipole arm and a second dipole arm and a second dipole that extends along a second axis, the second dipole including a third dipole arm and a fourth dipole arm and the second axis being generally perpendicular to the first axis, where each of the first through fourth dipole arms has first and second spaced-apart conductive segments that together form a generally oval shape.

Multi-band base station antennas having crossed-dipole radiating elements with generally oval or rectangularly shaped dipole arms and/or common mode resonance reduction filters

Antenna arrays may include a first plurality of radiating elements responsive to respective pairs of first radio frequency signals and a second plurality of radiating elements responsive to respective pairs of second radio frequency signals. A shared radiating element is also provided, which is responsive to a corresponding pair of first radio frequency signals and a corresponding pair of second radio frequency signals. This shared radiating element may be equivalent in configuration to the first and second pluralities of radiating elements, or may have a unique configuration relative to the first and second pluralities of radiating elements. The first plurality of radiating elements and the second plurality of radiating elements can be aligned as respective first and second spaced-apart and collinear columns of radiating elements, with the shared radiating element disposed about equidistant between the first and second columns.
