MICROWAVE FILTER BASED ON METAL-DIELECTRIC TUNNELS WITH AN EFFECTIVE PERMITTIVITY CLOSE TO ZERO.

摘要

Microwave filter based on metal-dielectric tunnels with an effective permittivity close to zero. The use of this type of tunnels allows a circuit to be miniaturized, unlike traditional filters. The filter may have two or more tunnels interconnected therebetween with transmission lines, where the inlet and outlet ports are arranged in micro-tape supplying lines.
