Problems solved by technology

[0007] The above-mentioned existing technologies all use the microstrip line to the surface structure. Since the microstrip line cannot be a single-layer metal, it must have a bottom metal ground, so the surface wave and the microstrip circuit cannot be integrated in one plane.
