Abstract: A base station antenna comprises a reflector assembly and a first radiating element having a first feed stalk and a first radiator. A base of the first feed stalk is adjacent the reflector assembly and the first radiator is adjacent a distal end of the first feed stalk. A center of the first radiator is offset from the base of the first feed stalk in a longitudinal direction that is parallel to a longitudinal axis of the base station antenna.

Abstract: A reflector for a base station antenna comprises: a body; and at least one slot provided in the body, where the at least one slot is configured for forming at least one stub-type filtering structure in the body. The stub-type filtering structure is configured for at least partially inhibiting an induced current in the body within an operating frequency band of a radiating element mounted behind the reflector.

Abstract: A base station antenna that may include radiating elements having tilted dipoles. For example, a base station antenna may include a reflector and a plurality of radiating elements, each radiating element mounted on the front surface of the reflector and having a support stalk and at least one dipole mounted to the support stalk. The radiating elements include a plurality of first radiating elements configured to operate in a first operating frequency band, and arranged in one or more first columns extending along a first direction; and a plurality of second radiating elements, configured to operate in a second operating frequency band different from the first operating frequency band, and arranged in one or more second columns extending along the first direction. At least one dipole of a first of the second radiating elements in at least one of the second columns is tilted around the first direction.
