Document Type and Number:
WIPO Patent Application WO/2019/159745
Kind Code:
A1
Abstract:
An antenna device (101) comprises: a substrate (1); a member 2 having, on side surfaces orthogonal to a first main surface (MS1) of the substrate (1), a first conductive portion (21) and a second conductive portion (22) facing each other; and a first coil antenna (31) and a second coil antenna (32) with winding axes orthogonal to the first main surface (MS1). In a plan view of the first main surface (MS1), the first coil antenna (31) is disposed closer to the first conductive portion (21) than the second coil antenna (32), and the second coil antenna (32) is disposed closer to the second conductive portion (22) than the first coil antenna (31). In the plan view of the first main surface (MS1), the first coil antenna (31) and the second coil antenna (32) are arranged such that a straight line passing through these two coil antennas intersects the first conductive portion (21) and the second conductive portion (22).
