Abstract |
|
Design and experimental analysis of beam repositioning system in microstrip patch antenna array using dumbbell shaped Defected Ground Structure (DGS) for Wireless application (2.4 GHz) was carried out in this study. For the practical application of this study phase shifters are used to control the relative position of the main-lobe direction. DGS has characteristics of disturbing current distribution which leads to phase variation. In our antenna, these dumbbell shaped DGS are engraved at different positions over the ground plane to achieve phase shifting of main-beam. The parameters of antenna such as gain reflection co-efficient, bandwidth are determined and compared with the antenna without DGS. Every position at which the dumbbell shaped DGS was placed, the radiation pattern was measured and compared among them. Further, it’s also observed that simulated antenna with DGS has the Bluetooth application in ISM short-range band. |
