Abstract :
Metamaterial like EBG (Electromagnetic Band Gap) structures are used in slotted microstrip antenna and mobile handset applications for increasing efficiency and better return loss characteristics. As we know that traditional microstrip antennas have inferior feature in case of bandwidth. In this paper an antenna with slotted ground plane and patch has been developed in which EBG structure is used as a metamaterial above the ground plane for reducing surface wave losses. This antenna has desirable characteristics for use in mobile communications at two frequency bands (2067-2245 MHz) covering UMTS band and (2390-2795 MHz) covering ISM band whereas antenna using EBG structure is working at three frequency bands covering GSM, UMTS and ISM band. The patch size of this antenna is relatively small and is compatible with integrated circuits, and with EBG structures it covers three frequency bands.
