本論文研究內容主要針對可貼附於水上載具之 UHF 頻段無線射頻辨識標籤天線進行設計，標籤天線阻抗會因依附於不同的物體而造成標籤天線與晶片間的共軛匹配改變，因而導致無法讀取。本內容之F型偶極標籤天線針對依附於玻璃進行設計，利用寄生金屬片產生耦合之容抗特性，激發一新匹配模態與原基本操作模態結合，得到工作頻率範圍為 857 ~ 960 MHz之一寬頻天線，最遠讀取距離約為 5 m。因隔熱紙於製程中夾帶金屬成份，對於電磁波之收發會造成干擾或衰減之影響，因此將具短路棒之標籤天線進行設計以應用於貼附有隔熱紙之玻璃上，本研究提出利用對稱式偶極天線透過短路棒使天線與接地背板相連結，利用雙路徑以激發雙操作模態，使工作頻段涵蓋 860 ~ 965 MHz，以符合 UHF 頻段之規格，最遠讀取距離約為 6 m ，其天線相關參數及特性探討將於本論文中提出說明與討論。

Some UHF RFID tag antenna designs are proposed to apply for marine vehicle in this thesis. Due to loading effects to make impedance mismatching between antenna and microchip, tag antenna may not properly function when it’s attached on different material. This study first proposes an F-shaped dipole antenna attached on glass. By introducing two parasitic strips inset along the closed loop of the input IC chip to generate coupling capacitance, a new resonant mode close to the first operating mode of the regular F-shaped dipole antenna is excited to enhance the operating bandwidth. The operating frequency range can be 857 ~ 960 MHz to obtain the bandwidth of 103 MHz for UHF band with the maximum reading range of 5 m. Due to glass film with metal material, this will cause interference and degradation for electromagnetic wave. To overcome the above problem, we propose a symmetrical dipole antenna with the shorting pins connected with the ground plane. Two resonant modes can be excited to obtain the operating frequency range of 860 ~ 965 MHz to meet the specifications of UHF RFID system. Details of the proposed UHF RFID tag antenna designs are described, and experimental results for the obtained broadband performance operated at 900 MHz band are presented and discussed.
