Abstract: A radiating element may have a dipole arm that may include a first conductive circuit loop and a second conductive circuit loop. The first conductive circuit loop may include at least one narrow conductive segment and at least one wide conductive segment, and the narrow conductive segment may present high impedance characteristics in at least one frequency band outside the operating frequency band of the radiating element to suppress at least partially the current in the at least one frequency band. A base station antenna may include a feed board and the radiating element mounted on the feed board.

Abstract: A patch radiating element that includes a feeder pillar and a patch radiator mounted on the feeder pillar. The patch radiator includes a first patch portion extending in a first direction and a second patch portion extending from an outer end portion of the first patch portion in a second direction. The second direction is different from the first direction. As a result, a space interval between adjacent patch radiating elements can be increased, thereby improving the isolation between the adjacent patch radiating elements so that beamforming of an antenna can be optimized.

Abstract: A base station antenna includes a column of radiating elements comprising first and second sets of radiating elements, each radiating element being configured to operate in a first frequency band that has first and second sub-bands. The second set of radiating elements is located above and/or below the first set of radiating elements. The antenna further includes a feeding assembly that is configured to feed first RF signals that are in the first sub-band and second RF signals that are in the second sub-band to the column of radiating elements, where the feeding assembly is configured to partially attenuate sub-components of the second RF signals that are fed to the second set of radiating elements more than sub-components of the first RF signals that are fed to the second set of radiating elements.

Abstract: A multi-band radiating array includes a reflector, a plurality of first radiating elements defining a first column on the reflector, a plurality of second radiating elements defining a second column on the reflector alongside the first column, and a plurality of third radiating elements defining a third column on the reflector between the first and second columns. The first radiating elements have a first operating frequency range, the second radiating elements have a second operating frequency range that is wider than the first operating frequency range, and the third radiating elements have a third operating frequency range that is lower than the second operating frequency range. Related radiating elements are also discussed.

Abstract: A first-band radiating element configured to operate in a first frequency band may be designed for reducing distortion associated with one or more second-band radiating element configured to operate in a second frequency band. The first-band radiating element may include a first printed circuit board. The first printed circuit board may include a first surface including a first feed line connected to a feed network of a feed board of an antenna. The radiating element may also include a second surface opposite the first surface. The second surface may include one or more first conductive planes connected to a ground plane of the feed board; and one or more first open-end traces coupled to the one or more conductive planes.
