Abstract: PURPOSE: A spiral antenna and an RFID(Radio Frequency Identification) tag apparatus using the same are provided to offer an electrically miniaturized structure using a conductor spiral structure and a T-type matching unit. CONSTITUTION: A first conductor spiral(120) and a second conductor spiral(130) are placed to face each other to a horizontal direction. The first conductor spiral and the second conductor spiral are rolled in a straight and spiral shape while keeping a line width and a line interval. A T-type matching unit is connected to the both ends of a feeding unit(150). The T-type matching unit performs the matching of the input impedance of the feeding unit and the impedance of the first conductor spiral and the second conductor spiral. The input impedance of the feeding unit is matched with the terminal impedance of a RFID(Radio Frequency Identification) tag chip. A substrate(160) has a dielectric material and a flexible property.

Abstract: PURPOSE: An isotropic broadband RFID tag is provided to connect two T-matching circuits formed on different layers to an isotropic antenna in parallel, thereby enhancing a broadband feature and an isotropic feature and drastically reducing the size of an area of the RFID tag. CONSTITUTION: A first substrate includes a tag chip(111), a first matching circuit(112), and an isotropic antenna(113) wherein the isotropic antenna is connected to the first matching circuit and both ends of the isotropic antenna are bent. A second substrate comprises a second matching circuit(131). A connection unit connects the first and second matching circuits with the antenna in parallel. Both ends of the antenna are bent twice. The bending of the first and second ends of the antenna is symmetrical.
