WIRELESS COMMUNICATION SYSTEM, ANTENNA MODULE AND ELECTRONIC DEVICE |
| 摘要 |
Provided is a wireless communication system which has excellent communication characteristics even between antenna modules having antenna coils between which there is a large difference in outside diameter. The wireless communication system includes: a first antenna module including a first antenna coil; and a second antenna module including a second antenna coil and capable of communication by receiving a magnetic field transmitted from the first antenna module, in which the first antenna coil and the second antenna coil have mutually different outside diameters, and, out of the first antenna coil and the second antenna coil, the antenna coil having a larger outside diameter is formed in such a way that the area of an opening portion inside the innermost perimeter of an antenna pattern is not more than 120% of the outside diameter area of the other antenna coil having a smaller outside diameter. |
