Abstract Defected ground Structure (DGS) and Defected Microstrip Structure (DMS) have been developed to improve characteristics of microwave devices and circuits, due to its band-stop property. It’s noticed that a spurious harmonic at 7.6 GHz appears in the antenna. In this paper, an effective technique of suppression of harmonics is proposed by using a dumb-bell shaped DGS and spiral shaped DMS in our antenna, which eliminates the 7.6 GHz undesirable mode. The dimensions of our antenna are optimized by using CST Microwave Studio tool.
