A research team from Murmansk Arctic University has created a radio communication and navigation system for ice-class vessels along the Northern Sea Route, including the route to the North Pole. This was reported by the Ministry of Education and Science of Russia.
A scientific team of teachers and students from MAU received a patent for a "Broadband Antenna" — the simplest, cheapest, and most innovative log-periodic antenna. In professional radio communications, the patented device can be used in the shortwave radio band to provide radio communications along the Northern Sea Route and guide ice-class vessels all the way to the North Pole.
Specialists have created an antenna that is easy to use and manufacture. Only a wire and a frame in the shape of a truncated triangle are needed to create it. The production process consists of winding the wire around the frame in one direction, then in the other, after which the ends of the wires are connected.
Project manager Vladimir Milkin, Associate Professor at the Department of Radio Engineering and Communications at MAU, said that for many years, pairs of classic volumetric helical antennas were used to create linear polarization. However, these devices were difficult to manufacture and use.
And the innovators at MAU compressed the spirals, turning them into a practically flat structure that implements linear polarization, without orthogonal components, as in "wave channel" antennas.
The Ministry of Science and Higher Education noted that the technology proposed by scientists opens up new perspectives for optimizing and improving both individual antennas and complex antenna systems.
