The antenna element includes a base sheet and a coil conductor on the upper surface thereof. The feed device includes a feed element and an RFIC. The feed element includes a base sheet and a first coil conductor and a second coil conductor on the upper surface of the base sheet. The first coil conductor and the second coil conductor are arranged on the base sheet such that magnetic flux generated in the first coil conductor and the second coil conductor constitutes a closed magnetic circuit. The feed device is adhered to a coupling portion of the antenna element. As a result, the RFIC is strongly coupled to the antenna element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna device and wireless device","description":"An RFID tag includes an antenna element and a feed device.
