Definitions

  • the invention relates to a method for changing a Absenkwinkels an antenna, in particular a belonging to a base station mobile radio antenna.
  • the mobile radio network is designed in the form of a cell, wherein each cell is assigned a corresponding base station with at least one mobile radio antenna for transmission and reception.
  • the antennas are constructed so that they usually radiate downward at a certain angle relative to the horizontal, whereby a certain cell size is determined.
  • the so-called UMTS network acquires importance for the next generation of the mobile radio network, the so-called UMTS network, the 2000 MHz band.
  • the antennas must be set with different angles of inclination.
  • the lowering or inclination angle which is also sometimes referred to below as the downtilt angle with which a mobile radio antenna of a base station radiates downwards relative to the horizontal
  • the inclination angle of the radiation pattern is changed.
  • the phase shifters can be adjusted accordingly, which usually requires that the setting must be made manually on the mobile radio antenna.
  • existing protective devices must be dismantled or re-assembled. This is naturally associated with a considerable installation effort.
  • WO 96/14670 A1 it has also been proposed to be able to set the downtilt angle differently by means of an electrical control device, wherein the controller of such a control device can be mounted, for example, in the base of such an antenna device or used as a mobile control device, which can be connected via a plug connection, if necessary, led out of the antenna control lines to the below the protective housing built-in adjustment for adjusting the downtilt angle to press.
  • the adjusting device has to be adjusted at least in the direction of a stop, in order then to travel therefrom for a predetermined distance. Due to the traveled distance then a downtilt angle is set differently depending on it.
  • An antenna with a remotely controllable unit for changing the lowering angle (downtilt angle) has also become known from EP 1 067 626 A2. According to this prior publication, a sensor is used which detects the detection position of the antenna in each case in order to ultimately read from a memory the corresponding data and make the antenna setting.
  • a satellite receiving antenna with an alignment capability of the antenna to a satellite for receiving programs has basically also become known from US Pat. No. 5,983,071 A. Also in this Vorverö pretung the use of memory units and interpolation is described to store certain data for controlling the satellite here and read.
  • Antennas with differently adjustable Absenkwinkeln are basically also known from US 5,512,914. From US Pat. No. 6,078,824, an electromagnetic circuit device for carrying out a reduction of the emission angle can also be seen.
  • the object of the present invention is therefore to provide an improved method for changing the downtilt angle.
  • the method according to the invention can be used in particular in connection with an antenna control device which can be retrofitted to a corresponding mobile radio base station outside the protective housing for the radiator elements (radome).
  • the manual adjustment from the outside is fundamentally state of the art.
  • the control device according to the invention is preferably characterized by the fact that it interacts with cultivation outside the protective housing of the antenna exactly with that control element, via which otherwise the adjustment can be made manually.
  • the antenna described in more detail with reference to embodiments uses a basically known transmission element, which can be manually operated outside the antenna protective cover, and which extends through a corresponding opening into the interior below the protective housing of the antenna to there, for example via a transmission linkage the one or to actuate the plurality of phase shifters for adjusting the downtilt angle.
  • This guided from the outside to the inside through the protective housing or a part of the rear or side plate of the support and / or protective cover of the antenna actuator preferably consists of a spindle which is rotatably guided in a corresponding threaded sleeve. By turning thus the threaded spindle can be adjusted in the axial direction between two end or extreme positions.
  • the method according to the invention can therefore be used in particular in connection with an antenna control device use, which is designed wholly or essentially as a complete unit or complete module. Therefore, this control device can be easily handled and mounted, and not only, as described above, in cooperation with an actuator provided outside the cover housing of the antenna device. Rather, the invention also provides that the complete unit or the complete module can also be mounted below the protective cover as a simple and easily manageable complete module if necessary and can be retrofitted if necessary. Also in this case, the retrofittable antenna control device is coupled to a corresponding actuator below the protective cover to adjust the phase angle of the antennas differently. As a significant advantage, it turns out that the antenna control device according to the invention can be mounted as a complete solution simply outside or inside the protective cover of the antenna. An assembly of a plurality of individual components possibly even at different locations below the protective cover of the antenna, as in the prior art, so falls away.
  • a corresponding electronic or electrical control device is retrofitted, it is preferably mounted only outside the protective housing of the antenna. This then acts directly with the actuation transmitter, i. in particular the spindle gear provided for the manual adjustment, via which a rotation of the spindle gear can be made via the motor drive belonging to the control device.
  • control electronics allocate two absolute position values to the two end stops.
  • the absolute positioning can then be carried out at least in one of these two positions.
  • the actuator should preferably be moved in the form of the spindle only in the respective direction until reaching the end stop. Reaching the end stop can also be detected and evaluated electrically / electronically by the control electronics.
  • the transmission or actuator is preferably initially moved in the form of the spindle to at least one of the two end stops and then moved back to the other end stop, the maximum displacement path can be detected by way detection, preferably in the form of the counted rotational pulses, via the two end stops a maximum Lowering angle assigned and above each interim angle, if necessary, also be interpolated by means stored in a table support values. As a result, any positions between the extreme positions can be absolutely controlled.
  • the respective current setting value can be stored in a non-volatile memory, in order then to carry out the relative adjustment when the adjustment is made again from this value.
  • a control device with an outgoing interface is used. All setting and monitoring functions can be performed at the command level via this interface.
  • a special controller or a computer with appropriate control software or even, for. the base station will be used.
  • the mechanical and electrical / electronic parts of the control device used are coupled in a fixed relationship with each other. This requires no special addressing the control unit. Preferably, however, the control unit can also operate in a mode "with addressing”. This opens up the possibility of controlling a plurality of electronic control units from a central point via only one command interface, ie to set several angles correspondingly to different antennas.

Usually arranged in a corresponding vertical orientation or slightly inclined downward in the circumferential direction lying several antenna cells radiating into different cells on a not shown in the drawings antenna mast.
  • Such a mobile radio antenna may have a plurality of radiators which can radiate in different frequency bands, wherein a different angle of inclination, a so-called downtilt angle, can be adjusted by changing the phase distances between the individual vertically stacked radiators 1, with which the mobile radio antenna 3 opposite the horizontal radiates downwards. As is known, this takes place via corresponding settings of phase shifter elements, reference being made in this respect to the previously known solutions.
  • a base station 71 with an antenna mast 73 is shown, to which a corresponding mobile radio antenna 3 is attached, which via Lines 75 is controlled by the base station or the command device, and about which the emission direction in an angular range ⁇ electronically more or less can be lowered.
