Cellular antenna and systems and methods therefor
View Patent ↗A cellular communications antenna including sensors for determining position and/or orientation of the antenna. Position information may be obtained using, for example, a GPS receiver or by triangulation. Orientation information may be obtained using, for example, an electronic compass and/or gyroscope and/or an inclinometer. Position and/or orientation information may be utilised locally to control attributes of the antenna or may be communicated to a central controller which may control attributes of the antenna. Signals may be sent to a central controller to indicate that an attribute of the antenna is outside a desired range.
1. A cellular communications antenna comprising:
an array antenna configured to produce a beam and mounted for adjustable orientation;
an antenna orientation sensor mounted on a back side of the array antenna, opposite radiating elements of the array antenna, and configured to develop a signal characterizing the orientation of the antenna;
a plurality of actuators for adjusting the physical orientation of the array antenna and for adjusting attributes of the beam; and
an antenna controller responsive to the sensor signal and configured to control the plurality of actuators to achieve a desired array antenna orientation and beam orientation or configuration, wherein at least some of the plurality of actuators adjust beam azimuth, roll, and down tilt of the array antenna, and wherein at least some of the plurality of actuators adjust beam elevation, azimuth, and width of the beam.
2. A cellular communications antenna as claimed in claim wherein the antenna orientation sensor includes an electronic compass, inclinometer, or a gyroscope.
3. A cellular communications antenna as claimed in claim including a global positioning satellite (GPS) receiver.
4. A cellular communications antenna as claimed in claim 1 including an RF receiver for receiving transmissions from known locations and determining the position of the array antenna by triangulation.
5. A cellular communications antenna as claimed in claim wherein the antenna orientation sensor is permanently fixed to the array antenna.
6. A cellular communications antenna comprising:
an array antenna for producing a beam;
antenna position and orientation sensors mounted on a back side of the array antenna, opposite radiating elements of the array antenna, and configured to develop a signal characterizing the position and orientation of the antenna;
a plurality of actuators for adjusting the physical orientation of the array antenna and for adjusting attributes of the beam; and
an antenna controller responsive to the sensor signal and configured to control the plurality of actuators to achieve a desired array antenna orientation and beam configuration, wherein at least some of the plurality of actuators adjust beam azimuth, roll, and down tilt of the array antenna, and wherein at least some of the plurality of actuators adjust beam elevation, azimuth, and width of the beam.
