“…The performance of this antenna was carefully studied by dissolving salt into pure water. Based on this design, a feeding probe loaded with nut and washer was introduced to improve the performance of the monopole water antenna [4]. Another monopole water antenna was presented in [5] by inserting a dielectric base between water and the ground plane to maximize the bandwidth.…”

This paper presents a study of sea-water monopole antenna at very high frequency (VHF) band for maritime wireless communications. The sea-water monopole antenna consists of a feeding probe and a sea-water cylinder held by a clear acrylic tube. The feeding probe is loaded with a disk on the top to improve the excitation of TM mode. A theoretical study of the sea-water monopole antenna based on the three-term theory is presented, which has not appeared in literature. Commercial software packages ANSYS HFSS and FEKO are used to simulate this antenna. Experimental results of a fabricated sea-water monopole antenna with a radius of 50 mm show reasonably good agreement with theoretical predictions. Measurement shows that the proposed seawater antenna has high radiation efficiency. Meanwhile, due to the transparency and liquidity of sea water, the proposed antenna is almost optically transparent and can be easily reconfigurable. The center frequency of the antenna is tunable by lengthening or shortening the water cylinder, while the bandwidth of the antenna can be adjusted by widening or narrowing the water cylinder.

A saline‐water monopole antenna array is proposed in this article. The saline‐water monopole antenna consists of a feeding probe and a saline‐water cylinder held by a polyvinyl chloride tube. The feeding probe is loaded with a mental disk on the top to improve the excitation of TM mode, and there is a teflon base between the water and ground to maximize the bandwidth. The saline‐water monopole antenna is placed in the middle of the ground, around which, four parasitic saline‐water monopoles are symmetrically placed so that a cross‐shaped saline‐water monopole antenna array is formed. By controlling the injection of the water and the heights of the water cylinders, the antenna array achieves reconfigurable frequencies and patterns with high efficiency. The commercial software ANSYS HFSS is used for the antenna modeling and simulation. The final design is fabricated and tested. A good agreement is obtained between the simulation and measurement results.

“…The interest on fluid antenna began in 2005 and 2006 when a major progress was made by H. Fayad and P. Record. Three papers on ionic liquid antenna and saline-water antenna were published in 2005 and 2006[6][7][8]. In 2011, Tam et al filed two US patents on electrolytic fluid antenna, which gave the components of their seawater antenna[1][2].…”

Tunable high frequency seawater antenna

This research is on the study and design of a tunable high frequency (HF) seawater antenna for military applications. HF is for the range of radio frequencies between 3 MHz to 30 MHz. This corresponds to a wavelength of 100 m to 10 m. Since the physical size of an antenna is determined by its wavelength, approximately half a wavelength, λ/2, the size of the HF antenna is large and requires significant amount of space for installation and implementation. In a small island such as Singapore where land space is limited, operation of HF communications becomes a challenge. The objective of this research is to design and implement a tunable HF antenna that requires minimum amount of land space. It is well known that the electrical conductivity of seawater is around 4 S/m. The idea is to make use of seawater to design an antenna such that the antenna can be "switched on" or "off" at will. By varying the length of the water stream, the frequency of the antenna can be varied. Along the coast or at sea, the implementation of the tunable seawater antenna is simple and practical. On land, such antennas can be implemented in reservoirs or as water features by altering the electrical properties of the water.
