| 摘要 |
<p>The invention concerns a communication element for a low frequency communication system by electromagnetic coupling, comprising at least an antenna transmitting and/or receiving an electromagnetic field in the form of a coil (2) arranged on a substrate plate (1) serving as support, said plate having a certain thickness. The coil has turns wound in the thickness of the substrate plate so that the sensitivity of the antenna can be improved without increasing the thickness of the communication element.</p> |
