This research is aimed at investigating the interaction between a broadband dipole and metamaterials. Metamaterials are artificial electromagnetic structures whose electric permittivity and magnetic permeability can be engineered to have parameter values not available naturally. Metamaterials are popular in modern day research due to their interesting properties. The affect of using metamaterials to alter the directivity of the broadband dipole antenna is the focus of this work. Different metamaterial unit cells have been designed to be used as near field components to achieve selective directivity and improved gain. The antenna and metamaterials are modeled in ANSYS HFSS, a full wave FEM electromagnetic solver. On achieving satisfactory results from the simulation of the bow tie antenna and metamaterial unit cell separately, the process is extended to the design of a bow tie antenna surrounded by a 4x5 array of edge coupled split ring resonators also known as complementary split ring resonators that exhibit negative permeability when excited by the axial magnetic field from the antenna. Unlike, the conventional dipole antenna with omni-directional propagation the new antenna is designed to have directional propagation, and improved gain.
