Document Type and Number:
Japanese Patent JP2673577
Kind Code:
B2
Abstract:
A timepiece (4), adapted to be worn on a part of the body, for example on the wrist, is provided with an antenna capable of capturing an electromagnetic field bearing radio-diffused messages. Measurements have shown that when close to the wrist the radial electric component (Er) and the azimuthal or tangential magnetic component (H phi ) were predominant. Consequently, in order to capture the first, a capacitive antenna the electrodes of which are parallel to the back cover (2) of the timepiece will be provided and, to capture the second, an inductive antenna including a winding the axis of which is parallel to the longitudinal direction of the bracelet (3) will be provided.
