摘要

摘要本研究旨在分析贴片天线在茶叶含水量测量中的应用。基于贴片天线的系统在接地面和导电贴片之间使用气隙。茶叶样品包含在气隙中。贴片天线设计的谐振频率为5 GHz。测量了茶叶样品在水分2 ~ 10%范围内的共振频率和S11参数。贴片天线的共振频率随茶叶含水量的增加而降低。然而，贴片天线的回波损耗随泡茶含水量的增加而增加。利用线性模型参数对茶叶水分含量进行预测。

Feasibility study of patch antenna for monitoring moisture content of made tea

Abstract This study aims to analyze the patch antenna for moisture content measurement of made tea. The patch antenna-based system uses an air gap between the ground plane and an electrically conductive patch. The tea sample is contained in the air gap. The patch antenna design has a resonance frequency of 5 GHz. The resonance frequency and S11 parameters are measured for tea samples in the moisture range of 2–10%. The resonance frequency of the patch antenna was observed to decrease with an increase in the moisture content of tea. However, the return loss of patch antenna was observed to increase with an increase in the moisture content of made tea. Linear model parameters were calculated for the prediction of the moisture content of tea leaves.
