| 摘要 |
The invention relates to an inductive electrical component (26), especially in the form of an antenna for a signal transmission device in the form of an electronic key, an ID transmitter, a chip card or the like, comprising a coil body (30) on which three coils (27, 28, 29) are arranged as coil windings. The longitudinal axes of the coils (27, 28, 29) are essentially orthogonally arranged on the coil body (30) in relation to each other, in such a way that the coils (27, 28, 29) have a reception and/or emission characteristic in all three spatial directions. A fourth coil (31) is arranged on the single coil body (30) for the transfer of energy, especially for operating the signal transmission device. The invention also relates to a closing system using one such inductive electrical component (26), especially for access and/or driving authorisation in a motor vehicle, independently of the manoeuvre, in the form of a KeylessEntry/Go functionality and/or as a remote/short-range operation. |
