MAKHACHKALA, February 28 – RIA "Dagestan". Dagestan State Technical University has obtained patents for two technological developments with potential applications in both military and civilian sectors.
The first innovation is a method for producing protective films based on vanadium oxide. The technique enables gas-phase deposition of a protective layer at relatively low temperatures—150 to 300 degrees Celsius—addressing a key limitation in semiconductor manufacturing. Earlier methods required significantly higher temperatures that risked damaging sensitive components. The new approach preserves metallization and semiconductor properties, potentially extending the service life and reliability of electronic devices.
The second patented invention is a dual-slot “Vivaldi” antenna featuring a compact design with an ultra-wide operating frequency range. Its structure incorporates three lobes on the substrate and two tapered slots, allowing for broader directional signal reception compared to conventional designs while maintaining a small footprint. Such antennas are relevant for radar and control systems requiring precise direction finding and stable communication under challenging conditions.
DSTU maintains active cooperation with industrial enterprises in the region, with most of its research and development efforts focused on addressing practical challenges in local industry.
