Abstract: Ultra-wideband dual-band cellular dual-polarization base-station antennas and low-band radiators for such antennas are disclosed. The low-band radiator comprises a dipole and an extended dipole configured 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 ?/4, for connection to the antenna feed. The extended dipole has anti-resonant dipole arms of approximately ?/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.
