本論文的內容主要針對RFID讀取器天線915MHz/2.45GHz雙頻做探討,提出單頻圓極化天線、雙頻圓極化天線之整合設計,再配合導引板的使用,達到雙頻提升增益之目的。文中使用印刷於FR4板的平面天線與槽孔天線,藉由等振幅輸出、空間極化相差90°與相位相差90°的方式製作圓極化天線,並探討導引板的相關參數,完成雙頻增益提升之效果。在頻寬方面包含RFID使用UHF頻段與2.45GHz頻段,滿足臺灣與美國所需之規範。
In this thesis, the dual-band 915MHz/2.45GHz RFID reader circularly polarized antennas are presented. At first, a single-frequency of 915MHz and 2.45GHz RFID reader circularly polarized antenna is demonstrated. The microstrip patch or printed slot for circularly polarized antenna was conducted. For obtaining the property of circular polarization, Wilkson power divider was used as the feed of the proposed antenna. Because the slot antenna has bi-directional radiation, the bi-directional radiation reader antenna is not suitable for commercial applications in many areas. So, the single directional radiation of the reader antenna will be obtained by using the director. Also, the director will enhance the antenna gain. The second antenna design was focus on the 915MHz/2.45GHz dual-frequency RFID reader antennas with single directional radiation. From the results, the bandwidth covers the RFID UHF band and 2.45GHz band to meet the required bandwidth in U.S.A. and Taiwan.
