Multi-band phased array antennas include a backplane, a vertical array of low-band radiating elements that form a first antenna beam, first and second vertical arrays of high-band radiating elements that form respective second and third antenna beams and a vertical array of RF lenses. The first, second and third antenna beams point in different directions. A respective one of the second radiating elements and a respective one of the third radiating elements are positioned between the backplane and each RF lens, and at least some of the first radiating elements are positioned between the RF lenses.

Multi-band multi-beam lensed antennas suitable for use in cellular and other communications systems

Lensed antennas are provided that include a plurality of radiating elements and a lens positioned to receive electromagnetic radiation from at least one of the radiating elements, the lens comprising a composite dielectric material. The composite dielectric material comprises expandable gas-filled microspheres that are mixed with an inert binder, dielectric support materials such as foamed microspheres and particles of conductive material that are mixed together.

Aspects of the present disclosure may improve the accuracy of the known azimuth determination techniques by employing more than two GNSS antennas positioned on a base station antenna. Techniques may use one or more combinations of the GNSS antennas to determine an azimuth of the base station antenna, which serve to improve accuracy of an azimuth determination.

An antenna with adjustable tilt angle includes: a mounting structure; an antenna mount fixed to the mounting structure; an antenna mounted to the antenna mount, the antenna configured to produce an antenna beam; a remote electrical tilt (RET) unit operatively associated with the antenna to adjust a pointing tilt angle of the antenna beam; a tilt pointing direction sensor mounted to the antenna, the pointing direction tilt sensor configured to detect the a pointing angle of the antenna relative to a baseline standard; and a controller operatively connected with the RET unit and the pointing direction tilt sensor, the controller configured to receive signals from the pointing direction tilt sensor and transmit signals to the RET unit to adjust the tilt pointing angle of the antenna beam based on the detected angle of the antenna.

Aspects of the present disclosure may be directed to a reconfigurable antenna system including a reconfigurable antenna capable of providing various types of radiation patterns without having to be replaced or needing its orientation changed. The reconfigurable antenna may create various types of quasi-omni directional radiation patterns of different shapes depending on the environment.

Circular base station antenna array and method of reconfiguring the radiation pattern

A system includes a cellular base station and a roadside unit. The roadside unit is configured to communicate data directly on a backhaul communication medium that connects the cellular base station to a controller for the cellular base station.

Combined cellular base station and roadside unit system having a common backhaul and related methods

An exemplary alignment module for a base station antenna has one or more accelerometers and one or more magnetometers. The one or more accelerometers are used to determine tilt and roll angles of the antenna, while the yaw angle of the antenna is determined using the one or more magnetometers and the determined tilt and roll angles. Using multiple accelerometers and/or multiple magnetometers can improve accuracy of angle determination. A service provider can determine when to re-align the antenna by monitoring the tilt, roll, and yaw angles remotely to detect changes in antenna orientation. Yaw angle determination can also take into account offset values corresponding to soft-iron effects, hard-iron effects, and factory calibration. The need to re-calibrate offset values following changes in local magnetic environment can be detected by comparing different sensor signals, such as the different magnetic fields detected by a plurality of magnetometers.

Alignment determination for antennas

A base station antenna system includes a plurality of sector antennas angularly spaced around a support structure at approximately equal azimuth angles. A feed network is coupled to the plurality of sector antennas and provides a common RF signal to the plurality of sector antennas and applies at least one phase difference to at least one sector antenna of the plurality of sector antennas. In one example, the base station antenna system includes first, second and third sector antennas angularly spaced at 120&#xb0; intervals and the feed network applies a 120&#xb0; phase difference to the second sector antenna and a 240&#xb0; phase difference the third sector antenna. In another example, the base station antenna system includes first, second, third and fourth sector antennas angularly spaced at 90&#xb0; intervals and the feed network applies a 180&#xb0; phase difference to the second and fourth sector antennas.

Method of forming broad radiation patterns for small-cell base station antennas

Methods of operating a cellular radio are provided in which a first power supply signal is transmitted from a power supply to a wireless power unit at least in part over a power cable. A second power supply signal is wirelessly transmitted from the wireless power unit to the cellular radio to power the cellular radio. Data is transmitted from a baseband unit that is associated with the cellular radio to a wireless transceiver at least in part over a data cable. This data is wirelessly transmitted from the wireless transceiver to the cellular radio. The data is then transmitted through an antenna that is coupled to the cellular radio.

Communications plugs are provided which include a printed circuit board having a plurality of elongated conductive traces and a plurality of plug blades. Each plug blade has a first section that extends along a top surface of the printed circuit board and a second section that extends along a front edge of the printed circuit board. Additionally, each plug blade may have a thickness that is at least twice the thickness of the elongated conductive traces. The plug blades may be low profile plug blades that are manufactured separately from the printed circuit board.
