DECOUPLING FILTER ON METAMATERIAL Russian patent published in 2015 - IPC H01P1/20 

FIELD: radio engineering, communication.

SUBSTANCE: decoupling filter on metamaterial comprises a single-layer or multi-layer dielectric plate shielded on one side, having through-holes arranged periodically in rows, each hole fitted with identical metal elements in the form of distributed oscillatory loops coupled by capacitive gaps and having geometric dimensions much smaller than the operating wavelength, each oscillatory loop being an impedance conductor in the form of a square which is open at the corners, the opposite sides of which are connected at the centre by a cross-shaped impedance conductor mounted in the hole of the dielectric plate on a hollow metal leg connected to the shield.

EFFECT: wider transmission band with a high Q factor and geometric dimensions smaller than the operating wavelength.
