DEVICE FOR BIDIRECTIONAL SIGNAL TRANSMISSION OF COMMUNICATION SYSTEMS THROUGH A METAL SCREEN Russian patent published in 2023 - IPC H04B5/02 

FIELD: radio communication systems.

SUBSTANCE: invention is intended for organizing bidirectional communication channels with devices located inside metal screens and can be used, for example, in medicine for exchanging data with implantable devices enclosed in a metal case; in robotics for data exchange with devices completely enclosed in a metal case. The device for bidirectional signal transmission of communication systems through a metal screen comprises two transceivers and two resonators placed on both sides of the screen. The first resonator is connected to the first transceiver, and the second one to the second transceiver. The resonators have a magnetic coupling coefficient k greater than the critical one. The central operating frequency of the device coincides with the frequency of the second maximum on the amplitude-frequency characteristic of the direct losses of the interacting resonators as measured without a screen.

EFFECT: bidirectional signal transmission of communication systems through a metal screen.
