[Prior Art] Radio identification (RFID) system or radio frequency identification system has many innovative developments in commercial applications such as supply chain management, anti-counterfeiting, and tracking, and more companies are using this technology. Improve production or management processes. The RFID system provides powerful identification capabilities to make supply transparency transparent. If RHD technology is integrated with business processes and applications, it can more effectively change the supply chain management of manufacturing or retailers and suppliers, suppliers and other partners. . The chip can also record a series of information, such as product, location, and flood season. The biggest advantage is that it can improve the efficiency of item management. At present, the item information is recorded on the barcode, and then the scanner scans the slimmer to obtain information. The RFID tag only needs to be sensed within a certain range, and can read a large amount of information at a time. On the other hand, the drawbacks of the design and application of conventional RFID antennas are mainly that the cost of production is too high. At present, the ratio of the conductor cost of the antenna to the majority of the production and materials of the entire RHD system is the cost. Therefore, in recent years, the manufacturing cost of the antenna has been improved by many processes, such as the use of a conductor silver paste in a roll to ι'οΐΐ process, or a screen printing, etc., to reduce the manufacturing cost. In the process, the amount of silver glue is the key to the cost of antenna production. 1379456 U.S. Patent No. 7,277,017 discloses an RFID tag with an antenna consisting of a dipoie antenna and an intermediate circuit (1.叩) (4), the purpose of which is to design a loop (ίοο) conductor to provide an inductance value to eliminate the wafer and The parasitic capacitance generated by the conductor connected to the wafer.

Furthermore, the traditional 137945.6 " RFID standard antenna design cannot adjust the impedance matching, making it difficult to control the antenna resonance frequency band.

Moreover, the RFID tag antenna has a special impedance matching network that can be adjusted at the impedance matching position to facilitate control of the antenna resonance frequency band. Figure 3 is a plan view showing an RFID tag antenna in accordance with an embodiment of the present invention. Referring to FIG. 3, the radio identification (RFID) tag 137945.6 is an impedance matching inside a radio identification (RHD) chip. The embodiment of the present invention derives an impedance matching network and is electrically connected by two segments. A dipole antenna with an oblique angle is connected to achieve an optimized impedance matching of the antenna, resulting in a good resonance effect. It should be noted that the antenna pattern 312 of the radio identification (RFID) tag can be used in any different conductor material, such as copper, copper glue, silver glue, aluminum, etc., to achieve a frequency response (902~928 MHz). With frequency bandwidth (50 MHz), the frequency response (860~960 MHz) can also be achieved. • Fig. 4 is a plan view showing the plane of the RFID tag antenna according to another embodiment of the present invention. Referring to Figure 4, a radio identification (RFID) device 400 includes a substrate 401 and an antenna pattern 412 formed on the substrate 401. The material of the substrate 401 is a rigid substrate, a flexible substrate, a paper, a cloth or a composite material of the above materials. For example, the substrate material may be a soft and hard substrate made of a glass material (FR4) or a polymer material such as PET or PI. According to another embodiment of the present invention, the substrate 401 may be a high dielectric constant material or a high magnetic permeability material. The patterned wire loop 412 is not limited to be formed on the surface of the substrate 401, and may be selectively embedded in the substrate .401. The antenna pattern 412 includes a patterned wire loop 418 disposed on the substrate 401. The wire loop 418 includes a plurality of longitudinal wire segments 41 5a-415h and a pair of transverse wire segments 413a, 413b connecting the longitudinal wire segment ends to form a matching network. It should be noted that the width and spacing of the longitudinal wire segments 4] 5a-415h may depend on the actual antenna characteristics requirements. A pair of extended wire arms are disposed on the substrate. The RFID tag device 520, and a microprocessor 530 process and transmit the sensing signals of the reading antenna. The above-mentioned radio identification (RF1D) tag communication system 500 has many applications in the UHF band, such as supply chain management, access control cards, and warehouse management systems. Furthermore, the dual-mode sensing function is available in the Gen2 specification, thus enabling the passive RHD's long-range, close-range dual-mode sensing mode. Embodiments of the present invention reside in maintaining antenna performance, reducing the cost of the antenna, and improving the adaptability of the antenna. In response to these demands, a special adaptive matching network is designed to make an adaptive adjustment for each UHF center frequency that can be arbitrarily adjusted, that is, to match the complex impedance of the RFID, thereby achieving a common vehicle matching, and maximum energy. transmission. The present invention has been disclosed in the above preferred embodiments, and is not intended to limit the scope of the present invention.
