Definitions

  • the invention relates to a radiocommunication antenna for a base station of cellular radiotelephone networks, and more particularly to an antenna for misalignment of the radiation lobe by a variable phase-shifter.
  • the tilt is the angle in the vertical plane of the direction of the maximum radiation of the antenna relative to the horizontal. This angle corresponds to a misalignment of the radiation lobe, generally caused downwards.
  • the “tilt” is said to be “mechanical” when the antenna is installed with a slope relative to the vertical.
  • the “tilt” is said to be “electric” when the internal structure of the antenna provides electrical phase shifts between the signals supplying the various elementary sources internal to the antenna, combined to obtain the desired radiation in the vertical plane.
  • variable phase shifters The variation of the electrical tilt angle is done by arranging one or more variable phase shifters inside the antenna.
  • the current state of the art makes that the variation of the phase shift is obtained by mechanical displacement of parts having an electrical function.
  • the usual arrangements of these variable phase shifters allow to drive them all together by means of a single actuator.
  • VETs manually controlled antennas
  • RET remotely controllable version
  • the object of the invention is to provide a variable electric tilt antenna by making extractable a fully integrated module in the antenna to ensure the transformation of a VET antenna into a RET antenna and vice versa.
  • This module will correspond either to the manual control for a VET antenna or to the motorized remote control for a RET antenna.
  • the invention therefore generally relates to a variable electric tilt antenna whose transformation between a manually controlled version and a remote control version (or vice versa) is effected by extracting an internal module from the antenna and replacement by another ensuring the new feature sought.
  • the antenna comprises a module, insertable in the antenna and extractable thereof, comprising a mechanical or electromechanical device cooperating with the actuating device to control the movement of the actuator when the module is mounted in the antenna. the antenna.
  • the mechanical or electromechanical device comprises a movable actuator block, either of the motor type, in particular for remote actuation, or of the manually actuated type, and the actuating device comprises a connectable means of removable to the actuator block.

  • the figure 1 is an example of an antenna used in cellular network base stations. Such an antenna is installed vertically (carried by a support structure like pylon, directly by a wall, etc.).
  • the antenna consists of an envelope 1, called a radome or hood, closed at its ends by an upper cap 2 and a lower cap 3.
  • This lower cap 3 comprises one or more coaxial connectors forming an antenna access for the aerials. radio signals.
  • Other embodiments or arrangements are possible.
  • a variable electric “tilt” antenna is distinguished from a fixed “tilt” antenna by the presence of the control member of the variation of the electric "tilt”.
  • the figure 1 thus represents an antenna whose electric tilt is manually modifiable, with the adjustment and locating organs of the electrical tilt located at its base, which is the most usual arrangement.
  • the piece 5 of hexagonal shape allows rotation to change the "tilt" of the antenna.
  • a sleeve 6 constitutes the locating member; it is moved inside the antenna directly by the actuator 13 ( figure 3 ) variable phase shifters, and it leaves more or less of the antenna when the part 5 is turned on itself.
  • This sleeve 6 has graduation lines that identify the value of the angle of "tilt” is set the antenna as the rotation of the part 5 in one direction or the other.
  • Other arrangements or other forms of the adjusting member and the register member are possible without questioning the principle of modularity described below.
  • the plate 7 supports, inside the antenna, a module transforming the action on the part 5 in a movement of the actuator 13 variable phase shifters.
  • This module can be extracted from the antenna by removing the screws 8 and disconnecting it from the actuator 13 of the variable phase shifters by unscrewing the sleeve 6 as described below.
  • a recess in the part 3 allows the passage of this module to the outside, recess closed by the plate 7 when everything is in place.
  • the same antenna in remote-controlled RET version is represented by the figure 2 .
  • the difference lies in the presence of a connector 9 for providing the energy required for the rotation of the motor and for exchanging the control signals from a remote unit.
  • These signals can respond to any protocol or specification without challenging the stated principle. If an electronic circuit is necessary to convert or interpret the signals exchanged, these circuits will also be fixed and / or integrated into the extractable module held by the plate 7.
  • the figure 3 shows an embodiment of the extractable module. In this figure, the plate 7 is not in place.

  • the module comprises an actuator block comprising a screw 10 and a piece 11 displaceable on the screw 10.
  • a bracket 12 provides the connection between the part 11 and the actuator 13.
  • a rotation of the part 5 or the motor 15 rotates the screw 10 which linearly moves the workpiece 11 and the bracket 12 fixed on the workpiece 11.
  • This displacement is here linear because, in this embodiment of the antenna, the design of the Variable phase shifters are based on a linear motion to vary them.

With this threaded sleeve 6 screwing on the screw body 14A of the screw 14 until said sleeve 6 abuts on the second portion 12B of the bracket 12, the actuator 13 of the variable phase shifters is well secured of the movement of the organs 11 and 12.
  • the actuator 13 and the second portion 12B of the bracket 12 are clamped between the screw head 14B of the screw 14 and the sleeve 6, thereby securing the actuating device.
  • this screw 14 remains engaged in the member 12 until the member 12 is visible. Similarly, when another module is put in place, it is possible to engage the screw 14 in the hole provided for this purpose in the member 12 before the member 12 is inside the antenna , therefore not visible which would make this commitment difficult, if not impossible.
