Title:
ANTENNA COIL
Document Type and Number:
WIPO Patent Application WO/2013/172336
Kind Code:
A1
Abstract:
Provided is an antenna coil in which it is possible to form a magnetic field in a desired direction in a highly efficient manner while suppressing leakage of magnetic flux into a space other than the space in which the magnetic field is formed. The present invention is provided with a main coil part (41) configured by providing a conductor wire (40) so as to surround a first reference axis (X1), and an auxiliary coil part (42) configured by providing a conductor wire (40) so as to surround a second reference axis (X2). The second reference axis (X2) is set so as to intersect the magnetic flux of the main coil part (41) at the end part (P), in the axial direction, of the auxiliary coil part (42). The main coil part (41) and the auxiliary coil part (42) are connected so as to form a closed circuit.
