A stripline circuit uses a flat strip of metal which is sandwiched between two parallel ground planes.The insulating material of the substrate forms a dielectric.The width of the strip, the thickness of the substrate and the relative permittivity of the substrate determine the characteristic impedance of the strip which is a transmission line.
