摘要
本論文研究的主要目的，是設計出附有特定商標之射頻標籤天線。並依不同應用環境，採用不同之基材及製作方式來實現此標籤天線，而使用商標設計之標籤天線也具有容易公司識別的效果。 本論文中，我們分別設計了附有中鼎工程公司及台灣積層公司商標之射頻天線，我們也引用相關RF技術及電路學中共軛匹配的觀念來設計天線。 我們藉由此觀念，設計出之商標射頻天線操作在有最大功率輸出，並具有良好之效能,我們以多種方式實作天線像是PCB蝕刻方式和利用凹版印刷真空蒸鍍法。 另外在凹版印刷真空蒸鍍法製程上，可能有蒸鍍金屬厚度不一情形。 故我們藉由電磁理論中之渦流觀念，設計一方法檢測天線之金屬厚度，這可以讓生產線上快速且方便使用檢查蒸鍍製程之穩定性以便進行即時修正。 最後說明此標籤天線具有商業應用之可能性， 而天線效能符合理論及量測。

附有商標之射頻標籤天線之設計並列摘要
The major purpose of this thesis is to design logo-based tag antennas of RFID. According to different applications, we also adopt different substrates and manufacturing ways. If the company’s logo or brand names are embedded into antennas, it is easy for identification of tag’s company. In this thesis, we design RFID tag antennas based on the Logos of CTCI Corporation and Taiwan Lamination Corporation. We adopt RF techniques and the complex conjugate matching concept from circuit theory for these designs. Through the concepts, the logo-based antenna that we designed has the maximum power transfer and the best efficiency in antenna operation. We realize tag antennas by many methods, for example, PCB etching and gravure printing and vacuum deposition technology. Sometimes, it may cause non-uniform problem of deposited metal thickness in the technology of gravure printing and vacuum deposition manufacturing process. Through eddy current concept from electromagnetic theory, we design a method to measure metal thickness of antenna. It can be fast and easy to check deposited metal thickness, and to correct the production line. Finally, to demonstrate the tag antenna that we design to be possibly realized in business, we show the antenna performance agreement of theory and measurement.
