Aspects of the subject disclosure may include, for example, receiving, by a double trombone shifter device, signals relating to one or more crossed-dipole radiating elements of an antenna system, performing, by the double trombone shifter device, polarization rotation of the signals to derive output signals having polarizations that are rotated in a manner that results in a virtual physical rotation of the one or more crossed-dipole radiating elements, and providing, by the double trombone shifter device, the output signals to enable avoidance of interference. Other embodiments are disclosed.

Dual shifter devices and systems for polarization rotation to mitigate interference

Aspects of the subject disclosure may include, for example, a polarization shifter including a lower substrate having disposed thereon first and second transmission lines for coupling to a feed network, an upper substrate having disposed thereon third and fourth transmission lines for respective communicative coupling to orthogonally-polarized elements of a radiating element, and a dielectric layer residing between the lower substrate and the upper substrate, the upper substrate being configured to mechanically couple to the radiating element, the dielectric layer coupling the first transmission line with the third transmission line and coupling the second transmission line with the fourth transmission line, the upper substrate being rotatable relative to the lower substrate to effect polarization adjusting for the radiating element to facilitate avoidance of interference or passive intermodulation (PIM). Other embodiments are disclosed.

Polarization shifting devices and systems for interference mitigation

Aspects of the subject disclosure may include, for example, detecting, by a monitoring system associated with a communication system, signals received at an array of orthogonally-polarized radiating elements of an antenna, causing, via a motorized drive assembly, the array of orthogonally-polarized radiating elements to sequentially rotate to a plurality of positions, obtaining, by a control system from the monitoring system and for each of the plurality of positions, data relating to signals from the array of orthogonally-polarized radiating elements, based on the data, determining, by the control system, an optimal position of the plurality of positions for the array of orthogonally-polarized radiating elements at which an impact of passive intermodulation (PIM) on the communications system is minimized, and controlling, by the control system, the motorized drive assembly to cause the array of orthogonally-polarized radiating elements to occupy the optimal position. Other embodiments are disclosed.

Method and system for detecting interference and controlling polarization shifting to mitigate the interference

Aspects of the subject disclosure may include, for example, a motorized drive assembly that includes a motor and a drive assembly, where the drive assembly has an axle configured to be disposed through a rotatable substrate of a polarization shifter for a dual-polarized radiating element, the axle being further configured to fasten, at a first end of the axle, to a support structure of the polarization shifter, wherein, when the motorized drive assembly is assembled to the polarization shifter, the motor is controllable to impart rotational forces, via movement of the axle, to the polarization shifter to effect polarization adjusting for the dual-polarized radiating element. Other embodiments are disclosed.

Method and system for driving polarization shifting to mitigate interference

Aspects of the subject disclosure may include, for example, receiving, by a radio frequency (RF) mechanical device, signals relating to one or more crossed-dipole radiating elements of an antenna system, performing, by the RF mechanical device, polarization rotation of the signals to derive output signals having polarizations that are rotated in a manner that mimics physical rotation of the one or more crossed-dipole radiating elements, and providing, by the RF mechanical device, the output signals to enable avoidance of interference. Other embodiments are disclosed.

Radio frequency (RF) polarization rotation devices and systems for interference mitigation

The present disclosure relates to antenna design for installation on small cell base stations. The antenna design corresponds to a conformal antenna design that fits into a traditional sun-shield of an outdoor base station. In another aspect, the antenna design supports multiple bands and multiple technologies. In a further aspect, the antenna design provides a gain pattern that allows installation of the small cells into directional sectors to further enhance the spectral efficiency while providing a single installation location. In still a further aspect, the design permits the form factor of the base station to meet unique and desirable aesthetic principals such as a modern curved surface and an attractive and distinctive height, width and depth ratio.
