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.

“…Another monopole water antenna was presented in [5] by inserting a dielectric base between water and the ground plane to maximize the bandwidth. In [6], a cubic water dielectric resonator antenna (DRA) with compact size was designed due to high permittivity and low loss of the distilled water at the low frequencies.…”

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.
