STRIP STRUCTURE PROTECTING AGAINST EXTRA SHORT PULSES IN DIFFERENTIAL AND SYNPHASE MODES Russian patent published in 2021 - IPC H04B15/02 

FIELD: physics.

SUBSTANCE: invention relates to a strip structure. The technical result is achieved due to the fact that the strip structure consists of a reference conductor and two parallel conductors as well as a dielectric medium consisting of a dielectric substrate and ambient air in such a way so that the reference and active conductors are located on one side of the dielectric substrate, and the passive conductor is located symmetrically with respect to the active conductor on the other side of the dielectric substrate, and the value of the minimum modulus of the difference in linear delays of the line modes, multiplied by the line length, is not less than the sum of the durations of the rise, flat top and decay of the pulse supplied between the signal and reference conductors, and from the side of the passive conductor through the air gap a similar structure is located centrally symmetrically with respect to the center of the cross-section of the entire strip structure, a rectangular cross-sectional electric shield is added, the width of the support conductors is greater than the width of the others, and their outer end side is connected along the entire length with the shield, there are equal air gaps between the shield and the conductors in the upper and lower parts of the structure, passive conductors are connected to the shield at the far end, all conductors are located at the same distance from the vertical axis passing through the center of symmetry.

EFFECT: attenuation of the interference signal in the differential and in-phase modes of interference.
