Title:
PLANAR COIL ARRAY, AND DISPLACEMENT SENSOR
Document Type and Number:
WIPO Patent Application WO/2024/013823
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a planar coil array having a simplified structure for electrically connecting a plurality of planar coils and also having the function of a low-loss electrical signal pathway. The planar coil array (AR) has: a first planar coil (SU1) having a first spiral shape in which a first conductor is wound counterclockwise or clockwise with respect to a first core; and a second planar coil (SU2) having a second spiral shape in which a second conductor, residing in the same layer as the first conductor, is wound with respect to a second core using the same winding as for the first planar coil, and in which there is an angular deviation from the first spiral shape.
