REFLECTION AND DIELECTRIC MEASUREMENT FOR SALINITY OF WATER USING MICROSTRIP LOOP ANTENNA AND DIELECTRIC PROBE

Abstract

This study was conducted to investigate the feasibility of loop antenna in gauging level of
salinity of water via electromagnetic wave reflection. High salinity cause adverse effect to environment.
When high levels salinity of water diffuse into soil, it declines values of land for human and animal
consumption. These impacts can cause tremendous monetary lost because the restoration of impairments is
extremely costly. Therefore, a reliable salinity detection system of water source is crucial. In this work,
reflection measurement was conducted using loop antenna in conjunction with network analyser for water
salinity detection. Dielectric probe will be then used for dielectric characterization due to different water
salinity. It comes to learn that the different level of salinity of water exhibit different dielectric properties
through reflection measurement. The increment of salinity leads to increment and decrement of dielectric
constant and loss factor, respectively. Similar observation can be found in reflection coefficient.
