設計以凹版印刷及真空蒸鍍作生產的射頻標籤天線
DESIGN OF RFID TAG ANTENNA BASED ON GRAVURE PRINTING AND VACUUM DEPOSITION TECHNOLOGY
摘要
本論文研究的目的,在於設計工作在915MHz的共軛匹配RFID天線, 以及設計利用LC共振工作在12.56MHz的高頻天線. 我們主要是利用以凹版印刷及真空蒸鍍作為天線的生產, 以達到製作快速且成本低廉的目標. 在本論文中,我們也引用了電路學中共軛匹配的觀念. 我們可以藉由此觀念來在各種不同阻抗下達到最大功率輸出的目的. 即使RFID晶片的實部或虛部阻抗因廠商有所不同，在匹配阻抗的設計之下也能達到最佳效能。 我們同時也看到了利用凹版印刷及真空蒸鍍技術將天線設計在市場上以很低的成本來量產的可能性. 而為了配合凹版印刷及真空蒸鍍製造的過程所使用的底材PET，本論文也對於PET之材料參數作了量測與分析. 利用量測與分析之結果希望能夠使得模擬與量測結果接近.

The major purpose of this research is to design a 915MHz RFID tag antenna base on unique features of complex conjugate matching concept, and the HF band RFID tag adopt resonance frequency to design in 12.56MHz. Here, we adopt gravure printing and vacuum deposition technology to manufacture, and it achieve both of fast manufacture and low cost. In this thesis, we also adopt the complex conjugate matching concept from circuit theory. Through the complex conjugate matching concept, we can achieve the maximum power transfer in different impedance. Even the different RFID chip’s real part and image part impedance are not the same, we can achieve the best efficiency under complex conjugate matching design concept. We have also seen the possibility to use gravure printing and vacuum deposition technology fabricating this RFID tag antenna design with possibly low cost on the marketplace. In the thesis also analysis dielectric constant and loss tangent of PET and the material parameters for the manufacturing process which adopt the gravure printing and vacuum deposition technology. We use these parameters in the design simulation and check it if close to the measurement results.
