Abstract

Abstract One of the reasons for many diseases such as diabetes, stroke, high blood pressure, kidney disease, etc., is the excess consumption of salt and sugar in the diet. So, to minimize these health problems, it is important to consume appropriate quantity of salt and sugar in the diet. This paper presents the design and development of a salt and sugar detection system using a low cost compact microstrip patch antenna. The salt and sugar detection system using a compact microstrip antenna is based upon the variation of antenna parameters in the solutions of different concentrations of salt and sugar. The defected ground structure (DGS) is utilized for decreasing the size and improving the performance of the proposed microstrip patch antenna. The antenna is fed by using a microstrip line and it resonates at 2.4 GHz. The designed antenna is simulated and optimized using the computer simulation technology (CST) microwave studio. The antenna with optimized dimensions is fabricated and measured. The measurements of the return loss of the fabricated microstrip patch antenna for various solutions with different concentrations of salt and sugar are performed. The measured results confirm that the proposed compact microstrip patch antenna is suitable to detect the concentration of salt and sugar in the water. From the measured results, it is observed that the return loss of the antenna decreases, when the concentration of salt and sugar is increased. The proposed antenna is also suitable for compact 2.4 GHz wireless local area networks (WLAN) applications.

采用紧凑型微带贴片天线的盐和糖检测系统
摘要糖尿病、中风、高血压、肾病等许多疾病的原因之一是饮食中过量摄入盐和糖。因此,为了最大限度地减少这些健康问题,在饮食中摄入适量的盐和糖是很重要的。本文介绍了一种使用低成本紧凑型微带贴片天线的盐和糖检测系统的设计和开发。使用紧凑型微带天线的盐和糖检测系统是基于不同浓度盐和糖溶液中天线参数的变化。缺陷接地结构(DGS)被用于减小所提出的微带贴片天线的尺寸和提高其性能。天线采用微带线馈电,谐振频率为2.4 GHz。利用计算机模拟技术(CST)微波工作室对所设计的天线进行了仿真和优化。制作并测量了具有优化尺寸的天线。对制作的微带贴片天线在不同盐和糖浓度的溶液中的回波损耗进行了测量。测量结果证实,所提出的紧凑型微带贴片天线适用于检测水中的盐和糖浓度。从测量结果中可以观察到,当盐和糖的浓度增加时,天线的回波损耗减小。所提出的天线也适用于紧凑型2.4 GHz无线局域网(WLAN)应用。
