Abstract: 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.

Abstract: 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.
