Planar inductive unit and an electronic device comprising a planar inductive unit
Abstract:
A planar inductive unit having at least one operating frequency is provided. The inductive unit comprises at least one inductor winding (120) having a first width (121) and a centre (122) and being arranged in a first plane. The inductive unit furthermore comprises at least one ground path (200) having a first section (205) extending in the first plane and at least a second section (210) with a second width (211) extending in at least a second plane.
Abstract(Chinese):

提供具有至少一个工作频率的平面感应单元。 感应单元包括具有第一宽度（121）和中心（122）的至少一个电感器绕组（120），并布置在第一平面中。 感应单元还包括至少一个接地路径（200），其具有在第一平面中延伸的第一部分（205）和至少第二部分（210），其中第二宽度（211）在至少第二平面中延伸。
