Recently, there are rapid developments in wireless communications, and in order to satisfy the IEEE 802.11 WLAN/WiMAX standards, the printed monopole antennas are required. A multiband planar monopole antenna fed by microstrip line feed with Defected Ground Structure (DGS) is presented for simultaneously satisfying Wireless Local Area Network (WLAN) and Worldwide interoperability for Microwave Access (WiMAX) applications. The proposed antenna consists of a rectangular microstrip patch with rectangular slit, including the circular defect etched on the ground plane forming DGS structure. The soft nature of the DGS facilitates improvement in the performance of microstrip antennas.
