摘要
此論文研究為利用13.56 MHz Melexis MLX90121射頻辨識讀碼積體電路與13.56 MHz Texas Instruments RI-I02-112A-03射頻辨識應答器實現13.56 MHz被動射頻辨識系統。主要涉及標準為ISO 15693，包含通訊協定說明、封包格式與基頻編碼方式等等。 射頻辨識系統主要由讀碼器與應答器來構成，具高資料密度、快速閱讀速度、良好機器可讀性、不易受灰塵影響和未經允許複製/修改之可能性低等優點，為眾多辨識系統中相當受歡迎的解決方案。 13.56 MHz被動射頻辨識系統透過近場電感耦合達到讀取器及應答器間之能量與資料的傳輸，因13.56 MHz線圈天線與匹配電路對無線功率傳輸與通訊距離之增進有重要影響，故此論文對其設計方法亦詳加探討。 為適妥控制MLX90121讀碼電路與RI-I02-112A-03應答器間之收發功能，此論文運用Microchip PIC16LF877A微控器及35個PIC16精簡組合語言指令設定讀碼電路相關組態暫存器、編碼與解碼，然後整合13.56 MHz被動射頻辨識系統，並量測其整體無線通訊過程之可靠性與系統距離。

This thesis implements a 13.56 MHz passive RFID system using the 13.56 MHz Melexis MLX90121 RFID reader transceiver IC and the 13.56 MHz Texas Instruments RI-I02-112A-03 transponder. The major research topics include the ISO 15693 standard, data packet format, communication protocol, baseband coding, and so on. An RFID system comprises a reader and a transponder, which finds numerous applications due to its high data density, fast reading speed, good machine readability, no influence of dirt, and low possibility of unauthorized copying/modification. The 13.56 MHz passive RFID system investigated in this thesis is based on inductive energy coupling and signal transfer between the reader and transponder in the near-field region. Since the 13.56 MHz coil antenna and impedance matching circuit have critical effect on wireless energy transfer and communication range, the design methods for the coil antenna and matching circuit are also discussed in detail. In order to facilitate proper wireless communications between MLX90121 reader transceiver IC and RI-I02-112A-03 transponder, the Microchip PIC16LF877A microcontroller and its 35 PIC16 assembly language instructions are utilized to set the contents of configuration registers of MLX90121. Lastly, the communication reliability and range of the 13.56 MHz passive RFID system implemented are tested in open sites.
