Title:
ANTENNA DEVICE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/181042
Kind Code:
A1
Abstract:
An antenna device (301) provided with: a planar conductor; an antenna coil (3) which is connected to a communication circuit, is proximate to the planar conductor, and is connected to the planar conductor; a first capacitor (C10) connected to the planar conductor; and a second capacitor (C20) connected to the antenna coil (3). The first capacitor (C10) and a first inductance forming portion (L10) of the planar conductor configure a first resonance circuit (RC1). The second capacitor (C20), the antenna coil (3), and a second inductance forming portion (L20) of the planar conductor configure a second resonance circuit (RC2). The first inductance forming portion (L10) and the second inductance forming portion (L20) share at least a part of each other.
