A circularly polarized hybrid liquid antenna

A circularly polarized hybrid liquid antenna is presented in this paper. The antenna mainly consists of a semi cylindrical container and two liquids contained in the container. The liquids are saline water and pure water. The impedance bandwidth of the antenna is 2.72GHz-3.68 GHz and the gain is 4.5dBi-5.3dBi. The antenna is fed by an L-shaped probe that deviates from the center. In all impedance bandwidth, it is a circular polarization antenna.
