COMMUNICATION DEVICE, ELECTRONIC TIMEPIECE, AND ANTENNA DEVICE |
| 摘要 |
An antenna of an electronic timepiece includes a ring-shaped antenna pattern formed on a top surface or bottom surface of a cover glass and another antenna pattern that is formed beneath the ring-shaped antenna pattern and is capacitively coupled with the ring-shaped antenna pattern. The resonant frequency of the antenna is determined by the antenna patterns. |

1. A communication device, comprising:
a communication module; a cover glass covering the communication module and having a transparent window; and an antenna, wherein the antenna includes:
a first antenna pattern that is looped and formed on a top surface or a bottom surface of said cover glass; anda second antenna pattern beneath the first antenna pattern and capacitively coupled with the first antenna pattern, and wherein a resonant frequency of the antenna is determined by the first antenna pattern and the second antenna pattern. |
