Rectangular microstrip GPS antenna using metamaterial structure with defected ground structure (DGS) / Akram Arif Ab Rahim

This thesis proposes the miniaturization and performance increment of a conventional microstrip antenna through the incorporation of Defected Ground Structure (DGS) to a metamaterial substrate. The substrate Rogers RO3003 (Er = 3 and h = 0.75mm) is used to design the antenna, as it is suitable to be...
