Seawater Antenna for High-Frequency Surface Wave Radar
Liquid antennas can be easily reconfigured, which means that the antennas can work at different frequency by adjusting the height of liquid surface. This paper presents that seawater antennas can be used in high-frequency surface wave radar. First, performance of seawater antennas is analyzed using Ansys HFSS. Then the measured results of a real seawater antenna are presented. The results show good agreement with the simulation and can be used in a range of 4–15 MHz.
