To provide a method and a device for optimizing a dielectric circuit board material for improving performance in a resonance line.

The resonance circuit for processing a radio frequency signal includes a substrate. The substrate is a meta material and can incorporate at least one substrate layer. The resonance line and at least one ground can be connected to the substrate. One end of the resonance line is short-circuited to the ground electrically, or can be opened electrically. A substrate layer can include a first region having substrate characteristics and at least one second region. At least one portion of the resonance line can be connected to the second region. A set of first and/or second substrate characteristics is changed discriminatorily, and permittivity and/or permeability can be changed in a selection region. A set of third substrate characteristics is also given to a third region.
