The present invention provides filter assemblies, tuning elements and a method of tuning a filter. A filter assembly includes a housing having a top cover, a bottom cover and at least one sidewall, the top cover, the bottom cover and the at least one sidewall defining an internal cavity, the housing configured to receive first through third radio frequency ('RF') transmission lines; a top metal sheet mounted within the internal cavity that has a plurality of openings that form a first hole pattern; and a bottom metal sheet mounted within the internal cavity that has a plurality of openings that form a second hole pattern. The top and bottom metal sheets are vertically spaced-apart from each other in a vertically stacked relationship within the internal cavity. The top metal sheet and the bottom metal sheet each include at least one resonator.

A base station antenna includes a first antenna having first and second spaced-apart columns of first radiating elements therein, which are configured to operate within a first frequency band. An active antenna system (AAS) is provided, which is configured to operate within a second, typically higher, frequency band. The AAS includes a second antenna within a space between the first and second columns of first radiating elements. These first radiating elements may include tilted feed stalks which support higher integration by enabling the first radiating elements to overhang at least a portion of the second antenna.

Base station antenna with high performance active antenna system (AAS) integrated therein

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.

Reconfigurable multi-band base station antennas having self-contained sub-modules

Base station antenna units include a first and second base station antennas that have respective first and second housings. The first housing includes a top end cap and the second housing includes a bottom end cap. A jumper cable that includes a first connector port is mounted in one of the top end cap or the bottom end cap, and a second connector port that is configured to mate with the first connector port is mounted in the other one of the top end cap or the bottom end cap. A longitudinal axis of the first connector port extends in a vertical direction and a longitudinal axis of the second connector port extends in the vertical direction.

Base station antenna units having arrays spanning multiple antennas that are connected by jumper cables

Base station antennas include first through fourth radio frequency ('RF') ports, a plurality of first combiners that are coupled to the first and second RF ports, a plurality of second combiners that are coupled to the third and fourth RF ports, and an array that includes a plurality of radiating elements that have first through fourth radiators, where first and second radiators of each radiating element are coupled to a respective one of the first combiners, and third and fourth radiators of each radiating element are coupled to respective ones of the second combiners.

Base station antennas having arrays of radiating elements with 4 ports without usage of diplexers

Techniques for automating delivery of data of a radio to a spectrum access system are provided. The data is used by the spectrum access system to use the data to control transmission of the radio to regulate interference in shared spectrum at an incumbent or primary user, where the radio is that of a secondary user.

Methods and systems for provisioning of parameter data of radios controlled by a spectrum access system

Techniques for optimizing antenna parameters of a radio configured to transmit on spectrum shared by incumbent user(s) are disclosed. The incumbent user has priority to use the shared spectrum over the radio. The antenna parameters are optimized to reduce interference to incumbent user(s) and/or other radios utilizing the shared spectrum whilst maintaining satisfactory coverage area.

Active antennas are provided that include a housing having a front surface, first and second side surfaces and a rear surface, where the front surface comprises a radome and the first and second side surfaces comprise respective first and second thermally-conducting frame members. These antennas further include at least one radio that is completely mounted within an interior of the housing. Each of the first and second thermally-conducting frame members includes a plurality of outwardly extending fins.

Base station antennas having fully embedded radios and housings with integrated heat sink structures

A system includes a remote electronic tilt phase shifter module, a motor, a mechanical linkage that connects the motor to the remote electronic tilt phase shifter module, a current management circuit that generates a motor control signal responsive to a current control signal, and a driver circuit that is configured to selectively connect the motor to a power supply in response to the motor control signal.
