摘要

设计了一种谐振频率为5 GHz的单环微波传感器，并利用ADS工具对不同样品材料进行了仿真。传感器为矩形环形，带耦合馈线激励。带线是铜和基材采取的罗杰斯$5880\left(\varepsilon_{r}=2.2\right)$。将待测电介质的食品材料置于传感器上方，使其完全覆盖传感器顶层。观察到每次频移时反射系数随衰减变化的一致偏移。对不同材料的频移和衰减进行了分析，并给出了拟合数据的方程。

Microwave Single Ring Resonating Sensor for Food Sensing

A single ring microwave sensor resonating at 5 GHz has been designed and simulated using ADS tool for various sample materials. The sensor is rectangular ring with coupled feedline for excitation. Strip lines are of copper and substrate taken is Rogers $5880\left(\varepsilon_{r}=2.2\right)$. The food materials whose dielectric is to be measured is placed above the sensor such that the material covers top layer of sensor completely. A consistent shift in the reflection co-efficient along with the variations in attenuation at each frequency shift was observed. The frequency shift and attenuation for respective materials is analyzed and an equation fitting the data has been given.
