PROBLEM TO BE SOLVED: To provide a method and an equipment increasing design latitude of radio frequency circuit, that is, furthermore, which optimize a dielectric circuit board material for improving performance in a single port resonant line. SOLUTION: A printed circuit for treating a radio frequency signal is described. The printed circuit comprises a substrate. The substrate is a meta-material and can include at least one dielectric layer. The dielectric layer has a set of primary dielectric characteristics in a primary region and can have a set of second dielectric characteristics in a second region. A dielectric constant and/or a magnetic permeability of set of second dielectric characteristics can differ from a set of the primary dielectric characteristics. A printed circuit can include a connecting earth connecting to a single port resonant line and the substrate. The dielectric characteristics can modulate dimensionality of the resonant line. The dielectric characteristics can modulate impedance, acutance, and/or capacitance of the resonant line. The resonance characteristic of the resonant line can be distributed through the substrate.
