New description: [New technical field] This creation is about the one-piece forming label, especially the RF identification label for the metal identification and the spring identification. Eight-body shaped antenna [Prior Art] = Identification (Aut0_ID) system popularizes everything in life due to low-cost strips. However, due to the low amount of information and the inability to programmatically, bar codes are also an obstacle to application. Therefore, a better solution is to use the 2 MIC +^% + (Smar" Card) as an electronic-beat delivery device, such as a lc credit card. However, this type of contact type IC card must provide power and transmission data through the contacts of the card reader. In use, it has disadvantages such as slow processing speed and wear of contact points. The contactless 1C card communicates with the card reader wirelessly. The power required by the card can also be transmitted through the wireless technology, by the card reader or by using the built-in battery. Because the transmission process of power and information is through radio frequency, the non-contact identification system is also called the Radio Frequency Identification (RFID) system. Due to the development of technology and the popularity of applications, the principle of the RFLD system can be simplified by storing data based on a tag that can be read and written by the reader through the radio. An RFID system consists of three main injuries, an RFID tag (Tag or Transponder), an RFID reader (Reader or Interrogator), and an information application that manages the transfer of data between the 5' M352141 System, etc. The tag usually consists of an antenna and an electronic chip, and the reader includes a wireless communication module (RF Module, which provides processing for transmitting and receiving signals), a control module (Control Module), and a set of coupling elements. The input/output interface (such as RS232 or RS285) is connected to an application system device (such as a PC). Another important feature for RFID is the power supply. The passive tag itself does not have a power supply. All the power required for operation must be converted by the RF electromagnetic wave provided by the reader. As for the active tag, the supply chip is included. A battery that operates the required power. Compare the advantages and disadvantages of both: Active tags have a longer sensing distance, but the life of the tag is limited by the life of the battery. Passive tags generate power in a different mode depending on the frequency. RFID using the HF band of 13.56 是 or less is a near-field electromagnetic induction method, and RFID of the UHF band of 900 MHz and 2.45 GHz uses a far-field electromagnetic wave coupling method. Therefore, the design of the antenna will be different due to the use of the electromagnetic frequency band to the south. 'General near-field electromagnetic inductance φ should be designed in the coil type (Coil), while far-field electromagnetic wave coupling is used in the Dipole antenna type. . The frequency of RFID use, the design of the antenna, the size of the electromagnetic wave power, and the amount of power consumed by the RFID chip are the main factors affecting the RFID reading distance. In addition, the surrounding objects also have an impact on the reading distance of the RFID tag, especially metal objects, and the problem of solving the metal influence can be adjusted from the label itself. If RFID is to be used in a car or other metal environment, the most troublesome thing is that the RFID is affected by the metal in the identification, so the design of the tag antenna must be corresponding to avoid the adverse effects of metal. This is also the case. The problem to be solved by creating the "6 M352141 RFID tag with integrated antenna".
