Abstract
Twin-beam base station antennas are provided. A twin-beam base station antenna includes a plurality of vertical columns of radiating elements that are configured to transmit radio frequency signals in a frequency band. The radiating elements have bent metal radiator arms including tip portions that face respective center axes of the radiating elements.
Claims20
A base station antenna, comprising:
- a reflector;
- and
- a plurality of vertically-staggered vertical columns of radiating elements that are on a surface of the reflector and are configured to transmit radio frequency (RF) signals in a frequency band,
- wherein a metal radiator arm of each of the radiating elements comprises a base portion that is parallel to the surface of the reflector and a tip portion that is not parallel to the surface of the reflector,
- wherein each of the radiating elements comprises a printed circuit board (PCB) that is parallel to the surface of the reflector,
- wherein the base portion of the metal radiator arm of each of the radiating elements directly contacts the tip portion and extends on a surface of the PCB and is parallel to the surface of the PCB, and
- wherein the tip portion of the metal radiator arm of each of the radiating elements protrudes either away from the surface of the reflector or toward the surface of the reflector.
A base station antenna comprising a plurality of vertically-staggered vertical columns of radiating elements that are configured to transmit radio frequency (RF) signals in a frequency band and that have bent metal radiator arms comprising tip portions that face respective center axes of the radiating elements,
- wherein each of the radiating elements comprises a printed circuit board (PCB),
- wherein a base portion of the metal radiator arm of each of the radiating elements is on the PCB, and
- wherein the tip portions of the metal radiator arm of each of the radiating elements protrude from a surface of the PCB.
A base station antenna, comprising:
- a reflector;
- and
- first and second vertical columns of radiating elements that are on a surface of the reflector and are configured to transmit radio frequency (RF) signals in a frequency band,
- wherein each of the radiating elements comprises a printed circuit board (PCB) that is parallel to the surface of the reflector,
- wherein a first metal dipole arm of a first of the radiating elements of the first vertical column comprises a first tip portion that protrudes away from the surface of the reflector, the first metal dipole arm comprising a first base portion that is on the PCB, and
- wherein a second metal dipole arm of a second of the radiating elements of the second vertical column comprises a second tip portion that protrudes toward the surface of the reflector, the second metal dipole arm comprising a second base portion that is on the PCB.
