Design of Dielectric Resonator Liquid Yagi-Uda Antenna (original) (raw)

This paper presents on modified the dielectric properties of liquid with varying salinity, that was based on yagi-uda structure. Dielectric resonator antennas (DRAs) can be made with a wide range of materials and allow many excitation methods [1]. Pure water does not work at high frequency (> 1 GHz), but increases the salinity of water that modifies the dielectric properties of water. The resonator column height determined the operating frequency [2]. These antenna shows that the salinity increases the antenna was resonated at different frequency. 
