Size reduction and bandwidth enhancement in metamaterial antenna / Umi Namirah Zakaria

This thesis presents a design of metamaterial patch antenna incoperates with Electromagnetic Band Gap (EBG) structure for WiMax application. The patch antenna was fabricated on RO3003 substrate together with three circular EBG structure on ground plane. The RO3003 substrate has relative permittivity...
