In the laboratories of the Łukasiewicz – Institute of Microelectronics and Photonics (IMiF) in Warsaw, scientists are developing substrate materials that would enable the transfer of a very high-frequency signal.

It is estimated that the implementation of 6G technology will take many years, but today Polish scientists are part of the work on the sixth generation of wireless communication technology.

According to Łukasiewicz – IMiF, scientists use LTCC materials as the base materials, which are characterized by “a low dielectric constant and a low dielectric loss factor”.

The low dielectric constant allows increasing the speed of propagation of the signal by reducing its delays and bringing the signal lines closer, while the low dielectric loss factor contributes to the reduction of energy consumption of the system and allows to increase the frequency selectivity.

LTCC (low temperature co-fired ceramics) technology contributes to the progress of miniaturization thanks to the possibility of using multi-layer systems. The substrates developed by the Łukasiewicz – IMiF are adapted to work in the frequency range of 0.15 to 3 THz, which corresponds to the frequencies provided for the 6G technology.

The 5th generation network offers a maximum data transfer speed of 20 Gb / s, while 6G is to provide a speed of up to 1 Tb / s. The 6G network is intended to be a combination of physical and virtual worlds with artificial intelligence and biological systems.
