Abstract :
The Electromagnetic bandgap (EBG) structures have been used to improve the performance of the antennas. In this work, an extensive design study of some specific antennas will be presented. The design of antennas with one-dimensional EBG, so called Defected ground structure (DGS) has been carried out for various parameters improvement. The present study includes dumbbell shaped slots in the ground plane of the antennas. The initial results are indicating that using a DGS in the ground plane of the planar structures increases their electrical length and prevent the propagation in a particular band.
