LETI: Antennas for the Internet of Things

2024: Product Announcement

LETI St. Petersburg State Electrotechnical University has made a breakthrough in the development of antenna systems for Internet of Things technologies: scientists have created innovative holographic W-band antennas (75-100 GHz), completely devoid of imported components and implemented on the basis of the domestic element base. This was announced at the end of May 2024 by the associate professor of the Department of Theoretical Foundations of Radio Engineering LETI Liubov Lyubina.

The prototypes of holographic antennas created by us are further supposed to be used in multi-subscriber systems of the Internet of Things, - explained Liubov Lyubina.

She added that unlike the existing solutions on the market, the new antenna systems differ in the use of affordable and budget production technologies with a complete rejection of foreign components. All stages of creating devices - from design to final assembly - were carried out exclusively by the engineering staff of LETI.

According to Lyubina, the development of Russian communication systems for the Internet of Things is a critical task, since without mass available equipment, the full deployment of this advanced technology will be impossible. Until 2024, the domestic industry was often forced to rely on foreign equipment, which created serious risks for uninterrupted operation of systems.

The new development not only has applied significance for import substitution, but also pushes fundamental science forward. As data traffic increases in urban environments, there is a need to master new, higher frequency bands, in particular 75-110 GHz. However, the presence of numerous signals in a cramped urban environment gives rise to problems with their spread - re-reflection, fading and other phenomena. These challenges are solved by innovative holographic metallodielectric antenna solutions developed in LETI.

The industrial partner of the university within the framework of the project was the Chelyabinsk manufacturer of radio electronics "PLANAR." The company provided domestic measuring systems for comprehensive testing of created antennas in a variety of conditions. The tests confirmed the versatility of the development and the possibility of its application both in industry and in the service sector.^[1]
