三菱展示可将海水喷泉用作无线电天线的SeaAerial技术

The point about the SeaAerial isn't that it's aquatic. This isn't the first seawater antenna – the US Navy has taken a keen interest in the idea in recent years, but so far it's been limited by the necessity of keeping the plume-spraying apparatus out of the water to prevent the circuit from grounding in the sea and killing the signal. Mitsubishi's innovation is an insulated nozzle that transmits the radio signal to the saltwater plume. According to the company, inside the nozzle is a quarter-wavelength tube of insulated material that physically separates the plume from the surrounding water and maintains the circuit.

Another factor in the SeaAerial design is that, though saltwater can conduct electricity, it is much less conductive than metals, which translates into poor efficiency as an antenna material. Mitsubishi claims that by running computer simulations it was able to determine the ideal plume diameter – allowing for a 70 percent increase in efficiency.

Mitsubishi is currently working on other conductive and transmutative liquids as new antenna materials and has applied to register SeaAerial as a trademark.
