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.

Abstract: A base station antenna comprises an array of radiating elements configured to emit electromagnetic radiation and an RF lens positioned to receive the electromagnetic radiation. The RF lens has a first surface facing the array of radiating elements and a second surface opposite the first surface. The RF lens is divided into a plurality of portions that extend from the first surface to the second surface, respectively, the plurality of portions having respective refractive indices for the electromagnetic radiation, wherein the plurality of portions are arranged, in a width direction of the RF lens, such that a first of the plurality of portions having the highest refractive index is in a middle portion of the radio frequency lens and others of the plurality of portions having lower refractive indices are on either side of the first of the plurality of portions.
