Patent abstract
A two-dimensional structure medium comprising a conductor pattern as unit cells formed on the upper surface of a substrate and a conductor pattern formed on the lower surface of the substrate and exhibiting a left-handed characteristic achieved without using a via by utilizing the interaction between an inductance component formed by connecting a part of a floating island pattern out of the conductor pattern on the lower surface of the substrate with a pattern as the ground portion and a capacitance component of parallel-plate mode formed by the conductor pattern on the upper surface of the substrate and the conductor pattern on the lower surface of the substrate.
