  • Metamaterial transmission line apparatus and method of implementing the same
    Patent number: 8344828
    Abstract: A metamaterial transmission line for transmitting an electromagnetic wave. The metamaterial transmission line may include a substrate including a substrate configured to include a an upper portion and a lower portion on which a ground plane is formed, a signal line configured to be formed on the substrate, and a defected ground structure configured to include an etched region and two metal portions, wherein the etched region is generated by etching a part of the ground plane and the metal portions extend from the signal line and are disposed on the etched region.
