Abstract

A monopole water antenna with a relative permittivity of 81 and a variable conductivity has been studied. Three issues are addressed in the paper. Firstly, the relationship between the conductivity and antenna radiation efficiency is investigated. Secondly, a new feeding design for the water antenna is proposed and a good return loss, radiation efficiency and radiation pattern are obtained. Thirdly, experiments are conducted in anechoic and reverberation chambers to evaluate its performance. Good agreements are achieved between the simulation and measurement results. With different conductivity, the antenna may be regarded as a dielectric resonant antenna, a conducting antenna or their combination. This type of antenna can be considered as an attractive alternative to conventional antenna for various applications.
