BROADBAND HIGH-FREQUENCY SIGNAL TRANSMISSION DEVICE Russian patent published in 2009 - IPC H01P5/08 

FIELD: physics.

SUBSTANCE: medium wave (lm) broadband high-frequency signal (16) transmission device (2) of conducting structure (7) with at least, one signal transmission circuit (11) and two main circuits (12) symmetrical to signal transmission circuit (11) and together forming coplanar transmission line (13). Conducting structure (7) is arranged on two opposite sides of, at least, one dielectric layer (18) of substrates of preset thickness (d), so that conducting structure (7) forms galvanic isolation overlapped within specified interfaces (9). Therefore interfaces (9) of conducting structure (7) transmit high-frequency signals (16) through electromagnetic interface (10). Herewith thickness (d) of substrate layer (18) is less than lm/4, and several electromagnetic interfaces (10) are arranged in-series.

EFFECT: ensured galvanic isolation with good transmission properties.
