Document Type and Number:
WIPO Patent Application WO/2017/006921
Kind Code:
A1
Abstract:
An antenna device (101) is provided with a feeder coil (5) connected to a first feeder circuit (81) with a first frequency band, a first electroconductive member (1) having a first main surface (PS1), a second electroconductive member (2) having a second main surface (PS2), a third electroconductive member (3), and first connectors (51A, 51B). The second surface (PS2) of the second electroconductive member (2) is arranged so that at least a portion opposes the first main surface (PS1). The area of the third electroconductive member (3) is smaller than the area of the first electroconductive member (1) when viewed from the vertical direction (Z direction) with respect to the first main surface (PS1). The first electroconductive member (1), the third electroconductive member (3), and the first connectors (51A, 51B) constitute part of a loop for a magnetic field antenna for the first frequency band. The feeder coil (5) is disposed so as to be closer to the third electroconductive member (3) than the first electroconductive member (1) when viewed from the Z direction.
