Abstract
A compact microstrip-fed planar ultra-wideband (UWB) monopole antenna with dual band-notched characteristics is proposed. The proposed design consists of a rectangular radiating patch and partial ground plane. Wideband matching is obtained by using the stair cased rectangular radiating element and slotted partial ground plane. A U-shaped slot resonator and an inverted U-shaped slot resonator are embedded in the feed line and radiating patch respectively for rejecting 3 GHz WiMAX band and 5 GHz WLAN band. The proposed antenna is printed on the FR4 substrate and is optimized by ANSOFT High Frequency Structure Simulator (HFSS). A prototype is fabricated according to the optimized parameters values, and the antenna characteristics are measured. The results show that the proposed antenna is of UWB characteristic and exhibits band rejection of 3 GHz and 5 GHz WiMAX and WLAN bands.
