The feed coil includes a magnetic core and a coil-shaped conductor, which is provided around the magnetic core. An RFIC is connected to the feed coil. The sheet conductor has a larger area than the feed coil. A slit that extends from a portion of the edge of the sheet conductor toward the inner side of the sheet conductor is provided in the sheet conductor. The feed coil is arranged such that the direction of the axis around which the feed coil is disposed is parallel or substantially parallel to the directions in which the sheet conductor extends. The feed coil is arranged such that the feed coil is close to the slit and one of coil openings at the ends of the feed coil faces the slit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna device and wireless communication device","description":"An antenna device includes a feed coil and a sheet conductor.
