Title:
ANTENNA DEVICE AND COMMUNICATION TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/166835
Kind Code:
A1
Abstract:
A base layer (21) is provided with a first main surface-side conductor pattern (11) on a first main surface and a second main surface-side conductor pattern (12) on a second main surface. The second main surface-side conductor pattern (12) is thinner than the first main surface-side conductor pattern (11). The first main surface-side conductor pattern (11) is provided with a conductor pattern (13) for coils, a first conductor pattern (14) for capacitors and a second conductor pattern (15) for capacitors. The second main surface-side conductor pattern (12) is provided with a third conductor pattern (16) for capacitors and a fourth conductor pattern (17) for capacitors. The first conductor pattern (14) for capacitors and the third conductor pattern (16) for capacitors, and the second conductor pattern (15) for capacitors and the fourth conductor pattern (17) for capacitors form two capacitors, and constitute an antenna device (101) together with the conductor pattern (13) for coils.
