Scientists have developed an innovative material for wireless communication, which has a bandwidth of almost 100%

An international scientific group of scientists with the active participation of Russian specialists from the Department of Technology of Electronics Materials of NUST MISIS has successfully created a completely new composite material based on barium hexaferrite and paraffin, which can be easily used in technologies for wireless transmission data.

And all because the material was able to pass 99.77% of the input signal without any distortion or attenuation.

New development of scientists and its prospects for the future

Currently, the so-called hexaferrites are actively used as magnetic materials in electronics, radio, as well as microwave technology (antennas and coatings that significantly reduce visibility).

So the materials under consideration have excellent magnetic properties and increased resistivity, which makes it possible to use the material in the microwave region with minimal losses.

In addition, this material is easy to obtain, and is also highly corrosion resistant and chemically stable.

Now 5G wireless communication networks are actively developing, and for their implementation materials are needed that will are able to increase both the range of data transmission and improve the quality of the transmitted signal by wireless way.

Therefore, scientists decided to look from a new angle at hexafferites, which were previously studied only as materials for radio absorption, and not as material for creating antennas for 5G systems.

So, in the course of numerous laboratory experiments, scientists have established that an increase in the concentration of strontium ions in barium hexaferrite led to a significant decrease in both dielectric and magnetic losses in the microwave range. It turned out that the created material is able to pass 99.77% of the input signal without any distortion or attenuation.

This fact opens up quite broad prospects for material in wireless communications. So using it, it will be possible to create highly efficient filters.

The scientists shared the results of the work done on the pages of the Journal of Alloys and Compounds.
