Abstract (en)
[origin: EP1840845A2] Provided is a door handle device incorporated with an antenna that can prevent the magnetic flux produced from the electro-conductive members from impairing the performance of the antenna. The door handle device comprises an antenna coil 11 for external communication formed by winding copper wire and a circuit board 10 including a ground pattern 32 and detection electrode patterns 33 and 34 that are received in a door handle 5, and the ground pattern 32 and detection electrode patterns 33 and 34 are each provided with a plurality of slits 32S, 33S and 34S extending in parallel with an axial line A around which the antenna coil 11 is wound. The provision of the slits prevents generation of eddy current in each electro-conductive pattern which otherwise would interfere with the performance of the antenna.
