Embodiment Construction

[0056] figure 1 A three-band antenna station is shown schematically, one base station BS1 , BS2 , BS3 being assigned to each of the three frequency bands to be transmitted. The individual radiators and radiator systems for the three-band antenna system are arranged below a shield 3 (generally within or below the radome 3) and are not shown in detail. In this regard see known solutions.

[0057] in accordance with figure 1 In the scheme, the radiator and the radiator device are arranged on the upper end of the antenna pole structure 5 under the shielding cover 3 . For each frequency band of each base station BS1 to BS3 two radio-frequency feeders 7 each run between the base station and the associated antenna radiator arrangement.

[0058] In addition, according to figure 1 In the solution of the present invention there is also an amplifier device TMA1 arranged close to the antenna, ie remote from the base stations BS1 to BS3, in which case the signals for controlling the mu...

Abstract

A multi-beamforming device is distinguished by the following features: the multi-beamforming device (M-RET) has at least one electronic communication interface (13) for controlling the multi-beamforming device (M-RET) in order to set the at least two polar diagrams differently, the multi-beamforming device (M-RET) comprises at least one drive device, preferably having an electric motor (23), and preferably a power supply (19), the multi-beam forming device (M-RET) comprises at least two first mechanical interfaces and / or coupling points (25; 25a, 25b, 25c; 25'; 25'a, 25 'b, 25'c), - a drive connection (27; 27a, 27b, 27c) acts at each of the at least two first mechanical interface and / or coupling points (25; 25a, 25b, 25c; 25'; 25 'a, 25 'b, 25'c), the at least one drive device (23) of the multi-beam forming device (M-RET) is connected via a multi-transmission (23') to the at least two mechanical interface and / or coupling points (25; 25a, 25b, 25c; 25'; 25'a, 25 'b, 25'c), wherein at least one of the plurality of drive connections (27; 27a, 27b, 27c) can be operated specifically in each case via the at least one drive device (23) and the associated control device, and wherein the number of interface and / or coupling points (25; 25a, 25b, 25c; 25'; 25'a, 25'b, 25'c) is greater than the number of drive devices (23).

Description

technical field [0001] The invention relates to a multi-beam forming device. Background technique [0002] Beamforming devices are used in particular in mobile communication technology, ie in mobile communication base stations, in order to adjust the main source of a mobile communication antenna differently with respect to the radiation angle of the mobile communication antenna. Depending on the angle of descent (which is often also referred to as "downtilt") relevant mobile communication units of different sizes can be illuminated and thus adjusted. [0003] Such a beamforming device is generally referred to as a RET unit, a so-called "remote electronic tuning" device, which is eg disclosed in WO 02 / 061877A2. However, not only can different downtilt angles be set in the vertical direction, for example by adjusting the phase shifters differently, by means of the beamforming device, but also, in particular in antenna arrays with multiple columns, for example using phase shif...
