Abstract: Base station antennas include a main module that has a first backplane that includes a first reflector. A vertically-extending array of first radiating elements is mounted to extend forwardly from the first reflector, and at least one first RF port is coupled to the vertically-extending array of first radiating elements. These antennas further include a sub-module that is attached to the first backplane. The sub-module includes a second backplane that has a second reflector that is separate from the first reflector. A vertically-extending array of second radiating elements is mounted to extend forwardly from the second reflector and is transversely spaced-apart from the vertically-extending array of first radiating elements. A plurality of second RF ports are coupled to the vertically-extending array of second radiating elements. The vertically-extending array of first radiating elements and the vertically-extending array of second radiating elements are configured to serve a common sector of a base station.

Abstract: A twin beam base station antenna includes a first array that has a plurality of columns of first frequency band radiating elements, the first array configured to form a first antenna beam that provides coverage throughout a first sub-sector of a three-sector base station. The radiating elements in a first of the columns in the first array have a first azimuth boresight pointing direction and the radiating elements in a second of the columns in the first array have a second azimuth boresight pointing direction that is offset from the first azimuth boresight pointing direction by at least 10°. The radiating elements in the second of the columns in the first array are electrically steered.

Abstract: Active antenna units and/or base station antennas are provided that include a reflector body with heat dissipation structures that can be directly exposed to environmental conditions during use. The heat dissipation structures have frequency selective surfaces and can be formed of sheet metal or provided as separate extruded or die cast members that can be coupled to the reflector body.

Abstract: A reduced wind load antenna includes: a radome having front, rear, and side surfaces; upper and lower end caps attached to upper and lower ends of the radome to define an internal cavity; and radiating elements positioned within the internal cavity and configured to transmit and receive radio frequency (RF) signals. The antenna includes at least one airflow separation delaying feature selected from the group consisting of: large radiused corners on the lower end cap; a domed upper end cap; a domed lower end cap; a plurality of protuberances on the front surface; a plurality of protuberances on each of the side surfaces; spiral ridges on the front surface; and a continuous protuberance on each of the side surfaces.
