SYSTEM FOR THE WIRELESS COUPLING OF A RADIO DEVICE

摘要

The invention relates to a system for the wireless coupling of a radio device, especially a mobile phone, said system comprising:·° a plurality of antennas (102a - 102e) which can be optionally operated for the wireless coupling of a radio antenna of the radio device, the antennas (102a -102e) especially being arranged adjacent to each other such that the radio device, within a range defined by the system and in optional positions and/or orientations relative to the plurality of antennas (102a - 102e), is in a position and orientation in which a radio signal transmission between one of the antennas (102a - 102e) or a plurality of adjacent antennas (102a - 102e) and the radio antenna of the radio device is subject to less attenuation than between the other antennas (102a - 102e) and the radio antenna of the radio device, ° a multiplex switch (104) which comprises a first HF signal connection (104a) for connection to an external connecting line and which is connected to a plurality of internal connecting lines (103a - 103e) of the system via which internal connecting lines the multiplex switch (104) is connected to one of the antennas (102a - 102e) or to a plurality of adjacent antennas (102a - 102e), the HF signal connection (104a) being connectible optionally to one of the internal connecting liens (103a - 103e) or to groups of the internal connecting lines by switching the multiplex switch (104), ° a detector (105) which is designed such as to detect a signal strength of a HF signal transmitted by one of the antennas (102a - 102e) or by a plurality of antennas to the HF signal connection (104a) by means of the multiplex switch (104), ° a controller that is connected to the detector (105) and that is designed such as to switch the multiplex switch (104) in such a manner that the antenna (102a -102e) or the antennas having the one or more radio connections to the radio device with the least attenuation, i.e. the antenna (102a - 102e) or the antennas that transmit the HF signal having the highest signal strength to the multiplex switch (104), is/are permanently connected to the HF signal connection (104a).
