Abstract
A base station antenna is provided. The base station antenna includes a reflector and a plurality of 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. Facing radiator arms of respective radiating elements in adjacent columns among the plurality of vertical columns have tip portions that protrude in different directions relative to one another, with reference to the surface of the reflector.
Claims20
A base station antenna, comprising:
- a reflector;
- and
- a plurality of 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 facing radiator arms of respective radiating elements in adjacent columns among the plurality of vertical columns have tip portions that protrude in different directions relative to one another, with reference to the surface of the reflector.
A base station antenna, comprising:
- a reflector;
- and
- a plurality of 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 at least a subset of the radiating elements comprises a plurality of metal radiator arms, each of the metal radiator arms comprising a base portion that is parallel with the surface of the reflector and a tip portion that is angled relative to the base portion, and
- wherein the base portion of the metal radiator arm and the tip portion of the metal radiator arm are contiguous portions of a continuous piece of sheet metal.
A base station antenna, comprising:
- a reflector;
- and
- a plurality of 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 first radiating element in a first column of the plurality of columns is equidistant from two radiating elements in an adjacent second column of the plurality of columns facing a first side of the first radiating element, and
- wherein a radiator arm on the first side of the first radiating element has a tip portion that protrudes in an opposite direction compared to tip portions of respective radiator arms of the two radiating elements in the second column, with reference to the surface of the reflector.
