| This thesis research has been conducted with an aim of investigating the effects of metamaterials on microstrip patch antennas. Metamaterials exhibit interesting properties such as single negative or simultaneous double negative values of relative permittivity and permeability, due to which they have gained immense popularity. The influence of metamaterials on traditional patch antennas has been a topic of focus throughout this research. Different metamaterial unit cells have been designed to possess satisfactory behavior in terms of permittivity and permeability. The use of metamaterials as a substrate for patch antennas has been explored, highlighting the possibility of designing electrically small patch antennas. Several metamaterial unit cells and modified patch antennas have been designed and modeled in Ansys HFSS, a highly competent full wave electromagnetic solver. On achieving a satisfactory results from a single patch antenna, the same concept has been applied to design a planar phased array patch antenna having 8x8 elements. The planar phased array antenna will be designed to enable beam steering from broadside toward the horizon. |
