Scientists have created a liquid antenna



Scientists have proposed a new design for a conical liquid antenna. The researchers analyzed how it works over a wide range of frequencies.

The proposed antenna has been tested with three types of liquids such as pure water, glycerin and sea water. The authors found that the device can achieve a voltage standing wave ratio of 1 to 2 in the frequency range from 300 to 850 MHz.

Simulation and experimental results confirm that the proposed compact and economical cone antenna provides a wide frequency range. At the same time, interestingly, the operating frequency is regulated by changing the height of the liquid inside the cone. It is also noted that the antenna is 30-40% shorter than a similar metal antenna, and the radio emission from it is omnidirectional.

This type of antenna is more flexible and cheaper.
