FREQUENCY-SELECTIVE HIGH-IMPEDANCE SURFACE BASED ON METAMATERIAL Russian patent published in 2016 - IPC H01P1/22 

FIELD: physics.

SUBSTANCE: invention can be used for creation of frequency-selective high-impedance surface. Present invention consists in that frequency-selective high-impedance surface comprises shielded one-layer printed circuit board, on one side of which is impedance array of related at least two capacitive gaps microstrip multi-coil Archimedean spirals, in centres of which are arranged metallised transition holes connected with common metal screen, capacitive gaps are made in form of microstrip coplanar lines.

EFFECT: technical result is design of a frequency-selective high-impedance surface, which has negative values of effective dielectric and magnetic permeability, as well as surface impedance, tuned in this frequency range, and significantly exceeding wave impedance of free space.
