本論文基於近場自我注入鎖定(near-field-self-injection-locked，NFSIL)原理，發展一套液體複數介電係數量測系統，量測待測液體為葡萄糖水溶液及酒精水溶液。此系統由自我注入鎖定迴路及解調電路組成，自我注入鎖定電路係由非對稱共面波導(asymmetrical coplanar waveguide，ACPW)共振器作為振盪器的選頻及感測元件。待測液體引發共振器的相位變化，相移變化注入回振盪器中，產生對應於待測液體的頻率偏移。振盪器輸出訊號進入解調器後，將振盪器中的頻率偏移轉換成電壓輸出，輸出偏壓進行校準後，可用來計算待測液體的複數介電係數。本論文所提出之量測系統，具有低成本、高精準度及高靈敏度之優點。

This thesis develops a near-field-self-injection-locked (NFSIL) sensor for liquid permittivity measurement. The water-glucose mixtures and water-ethanol solutions are chosen as liquid under test (LUT). This permittivity sensor mainly consists of a NFSIL sensing oscillator and a demodulation circuitry. The “asymmetrical coplanar waveguide (ACPW) resonator” simultaneously plays the roles of the sensing device and frequency selective element for the sensing oscillator implementation. As LUT is placed upon the ACPW resonator, it will introduce a transmission phase shift. This phase-shifted signal then injects into the sensing oscillator, and leads to a frequency deviation according to the permittivity of the LUT, namely a frequency-modulated (FM) signal. When this FM signal is sent into the demodulation circuitry, the frequency deviation will transfer into the in-phase (I) and quadrature-phase (Q) output voltages. After performing the sensor calibration using the reference liquids, the complex permittivities of the LUTs can be related to the measured I/Q voltages by the polynomial equations. The proposed permittivity sensor in this thesis has the advantages of low cost, high measurement accuracy, and real-time response.
