st. Petersburg State Electrotechnical University (LETI) have developed flexible microwave antennas for drone control. This was reported to socialbites.ca from LETI.
st. “We have developed a series of lightweight and compact microwave antennas that allow you to control drones of various types and purposes and transmit video images,” said Yury Antonov, Associate Professor of the Department of Theoretical Foundations of Radio Engineering in St. Petersburg. Electrotechnical University “LETI” told socialbites.ca.
According to him, foreign analogues of such antennas exist, but the geopolitical events of the past two years have shown that some foreign suppliers can easily refuse to work with the drone manufacturers for which these antennas are designed.
“Drone antennas may be needed quickly and in significant quantities. Our antenna was created to organize domestic production. Especially at our university, they can gather in small batches for industrial partners,” said Antonov.
Inexpensive construction materials (brass, PVC) and manufacturing technologies (for example, laser cutting of metals) were used to manufacture the components and assemble the antennas. To quickly set up the device, the scientists developed the circular antenna array, making it flexible and diverse. Changing the position of each array element allows you to tune the antenna to the operating frequency of a particular drone several times faster.
Antennas created thanks to the use of widely used assembly technologies as well as domestic components can be put into production quickly.
Previously on LETI educated Neural network for drawing pictures in the style of Claude Monet and Arkady Rylov.
