Abstract: A Dual Notch ultra wideband antenna (UWB) is presented in this communication. The dual notch bands covers the WLAN and WiMAX frequencies. The Ultra wideband is achieved by introducing multiple techniques into a basic antenna. The basic radiating element is a rectangular patch with a pentagonal slot at the center for which the bottom two edges of the patch are truncated in steps. A ground with a rectangular slot at the middle is considered. The cumulative effect of edge truncated slotted patch and partial defective ground plane will generate ultra wideband. To generate notch bands two stubs are loaded into the pentagonal slot there by enabling isolation in the WLAN and WiMAX frequencies. Proposed antenna is having a bandwidth of 10.37GHz ranging from 3.08GHz to 13.45GHz with isolation ranging from 3.66GHz to 3.86GHz and 4.9GHz to 5.6GHz.
Keywords: Dual Notch, Partial Ground, Slotted Patch, Ultra Wideband.
