Title:
ANTENNA DEVICE AND ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/056422
Kind Code:
A1
Abstract:
An antenna device (301) includes: a first planar conductor (111); a second planar conductor (210) that faces in parallel the first planar conductor (111); and a coil element (20) that uses the parallel direction of the first planar conductor (111) and the second planar conductor (210) as a winding axis, and has a first coil opening end (E1) and a second coil opening end (E2) facing the first coil opening end (E1). The first planar conductor (111) has a conductor outer edge (111es), and a conductor opening (OP) having a section connected to the conductor outer edge (111es). At least part of the conductor opening (OP) is located within a conductor overlap area (OA) where the first planar conductor (111) and the second planar conductor (210) overlap in a plan view of the first planar conductor (111). The first coil opening end (E1) of the coil element (20) does not overlap with the second planar conductor (210) in a plan view of the first planar conductor (111), and the second coil opening end (E2) of the coil element (20) overlaps with the conductor opening (OP) and the second planar conductor (210) in a plan view of the first planar conductor (111).
