Document Type and Number:
WIPO Patent Application WO/2004/095636
Kind Code:
A1
Abstract:
An antenna device (1) comprising an antenna unit (2) consisting of an antenna core unit (5) provided with a soft magnetic element (51) having a conductivity and a conductor wire unit (6) attached to the antenna core unit (5). At least part (e.g., core sheet (50A)) of the antenna core unit (5) is used as a sensor electrode capable of detecting an object. The sensor electrode can be used as an electrostatic capacity type sensor electrode or the like. Accordingly, an antenna device having an antenna unit provided with an antenna core unit commonly used by both an antenna function and a sensor function, and a door-knob device are provided.
