FIELD: physics.
SUBSTANCE: invention relates to microwave technology and can be used in selective paths of receiving and transmitting systems. Invention is a microstrip ultra-wideband filter having a substrate with a relative dielectric permeability ε and thickness d, on one side of which a metal shield is made, and on the opposite side of the substrate there is a coiled irregular stripline conductor, wide and narrow sections of which are connected to each other in cascade.
EFFECT: improved frequency-selective properties of a microstrip ultra-wideband filter.
