(EN) ANTENNA AND RADIO TIMEPIECE USING THE SAME, KEYLESS ENTRY SYSTEM, AND RF ID SYSTEM (JA) アンテナ並びにこれを用いた電波時計、キーレスエントリーシステム及びRFIDシステム | |||||||||||
| Abstract: |
(EN) A highly sensitive magnetic sensor-type antenna provided in a metallic housing, a radio timepiece into which the antenna is integrated, a keyless entry system, and an RF ID system, where a problem of eddy current loss is eliminated from the antenna without increasing installation area and volume. The antenna is constructed by bending an end section of a magnetic core of the antenna in the direction to separate from a metallic housing, or by providing an auxiliary magnetic path member having a smaller specific magnetic permeability than the magnetic core, or by receiving the magnetic core in a case made from a magnetic material.
