Antenna model 1 is the combination of monopole on front side and Defected Ground Structure (DGS) on back side. Antenna model 2 is the combination of monopole on front side and EBG loaded DGS on back side. Monopole antenna with DGS is resonating at dual band and monopole with EBG and DGS is resonating in the wideband. Both the designed antennas are covering operational bands of Worldwide interoperability for Microwave Access (WiMAX) and Wireless LAN (WLAN) with omni directional radiation pattern and stable gain. The proposed antennas are having the advantages of simple fabrication, compactness and excellent radiation characteristics which can be applied to wireless mobile communication system.
