Abstract
A highly efficient thin slot antenna having a cavity and an RFID tag device are provided, in which such flexible properties can be provided to the antenna that the antenna can be worn on the curved surface of a human body, an object, or the like as well as the antenna can be relatively freely deformed, and changes in the characteristics caused by deformation and changes in the characteristics caused by a product to mount the antenna thereon. are extremely small. Conductive foil such as aluminum or foil vapor deposited with conductive metal such as aluminum is used to form a bag shape for configuring a bag-shaped product having a cavity (). A relatively soft dielectric sheet () is provided inside the cavity (), and a slot () is provided lengthwise on one side of the bag-shaped product at the center position in the width direction.
