Title:
ANTENNA DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/122764
Kind Code:
A1
Abstract:
This antenna device is provided with: a wiring substrate (110); a conductive member which is formed on a surface of the wiring substrate (110) and has a first conductor part (11) and linear second conductor parts (21A, 21B) which conduct electricity therebetween; a coil element (20) having a coupling coil to which a power supply circuit is connected; and a capacitor (3). The first conductor part (11) has a conductor opening (OP) and a gap (G1) that connects an outer edge of the first conductor part (11) and the conductor opening (OP), and the capacitor (3) is disposed to cross over the gap (G1). The second conductor parts (21A, 21B) are connected to two points on an inner edge of the conductor opening (OP) and form a loop-shaped current path together with a portion of the first conductor part (11) and the capacitor (3). The coupling coil of the coil element (20) is magnetically coupled to the loop-shaped current path.
