Document Type and Number:
WIPO Patent Application WO/2023/032510
Kind Code:
A1
Abstract:
The present disclosure provides a coil element of which an inductance component and a capacitance component are reduced while maintaining a high coupling factor, an antenna device including the coil element, and an electronic apparatus. A coil element (10) of the present disclosure comprises a coil (L1) and a coil (L2) which are configured in an insulator (1). In the coil (L1), a plurality of first conductor patterns (21) are connected in parallel, and a second conductor pattern (22) is connected in series to the plurality of first conductor patterns (21). In the coil (L2), a plurality of third conductor patterns (23) are connected in parallel, and a fourth conductor pattern (24) is connected in series to the plurality of third conductor patterns (23). The coil (L1) and the coil (L2) are disposed in the insulator (1) with the second conductor pattern (22) and the fourth conductor pattern (24) opposite each other.
