本論文的研究主題為應用於金屬環境之無線射頻辨識標籤天線之設計,三款天線皆應用在UHF頻段,所使用的晶片為Alien Higgs-4晶片,第一款天線為使用接地面天線的方式設計,使用一個開槽孔的饋入方式激發接地面輻射,最大讀取距離可達9.8公尺,第二款天線為一款可貼附於金屬材質之標籤天線,延用先前所提出之開槽孔饋入方式,並在天線上加入適當長度與數量的槽縫來延長共振路徑以及提高增益,可達到縮小整體體積以及增加讀取距離之效果,最大讀取距離可達7.5公尺,最後一款天線為同樣可用於金屬表面之圓極化射頻辨識標籤天線,採用L型傳輸線耦合饋入的方式配合末端短路的設計來調整天線之輸入阻抗與晶片達到共軛匹配,並且配合四周之T字型槽孔來達到圓極化的效果,讀取距離可達到4.8公尺。
Three UHF RFID tag antennas designed for Alien H4 chip are presented in this thesis. The design techniques of tag antennas applied to around metal surface are especially addressed.
The first antenna is a ground radiated antenna. It uses an open slot structure to excite the ground to radiate energy. The second antenna use the first structure and etching four slits around the antenna which is attached to the metal surface. This design allows the tag to improve the performance to metal effects. The last one is a circularly polarized tag antenna, which is using an L-type coupling feed line to excite horizontal and vertical currents, and adjusting the unequal length slot to produce the circular polarization wave. This antenna also has a good performance for attaching on the metal surface.
