Metamaterials, also known as left-handed metamaterial(LHM) is a material that have simultaneously negative value of permeability and permittivity. LHM is an interesting material to be investigated where this artificial material has several unique properties such as the backward wave and the focusing effect inside it slab. The history of LHM was started from Veselago when he made a theoretical speculation of this artificial material that exhibit negative permittivity and negative permeability. Thirty four years later, on 2001, Smith made the first prototype structures of LHM. The LHM is a combination of Split Ring Resonator (SRR) and thin wire (TW). Since the introduction of LHM twelve years ago, a lot of researcher interested in investigating this artificial material and several of them was using LHM to improve the properties of the microwave devices such as antenna and filter. Many papers have been published about the LHM integrated with antennas and their properties have been analyzed. By 2003, researchers had verified that not only were these engineered materials possible, but they also could enable "perfect" lenses that were nevertheless flat. The focusing affect of LHM made a low gain antenna becomes directive and have an increment of gain.
