Abstract: PURPOSE: An isotropy tag antenna having a PIFA structure is provided to maintain a wide operation range by tuning an antenna structure regardless of the input impedance of a feeder. CONSTITUTION: An isotropy tag antenna comprises two PIFAs(Planar Inverted-F Antenna)(110), two T matching networks, and a feeder(170). Two FIFAs are printed on the antenna substrate to face each other. Two T matching networks connect two PIFAs. The feeder is formed between two T matching networks. The thickness and length of two PIFAs are controlled to reverse the directions of currents flowing in two PIFAs.

Abstract translation: 目的：提供具有PIFA结构的各向同性标签天线，以便通过调谐天线结构来保持较宽的工作范围，而不考虑馈线的输入阻抗。 构成：各向同性标签天线包括两个PIFA（平面倒置F天线）（110），两个T匹配网络和馈线（170）。 两个FIFA被打印在天线基板上以彼此面对。 两个T匹配网络连接两个PIFA。 馈线在两个T匹配网络之间形成。 控制两个PIFA的厚度和长度以反转在两个PIFA中流动的电流的方向。

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.

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.
