Abstract
A compact, low-profile and co-planar Ultra Wideband (UWB) antenna with dual Band from 3.4 GHz to 5.5 GHz (WiMAX/WLAN) notch features has been discussed in this paper. The proposed prototype is fed by CPW and designed on a 1.6 mm FR-4 substrate and 23×26 mm2 plane area. The frequency range from 3.1 GHz to 10.6 GHz of UWB will be covered by the proposed antenna. A C-shaped slot two symmetrical rectangular slots have been put in trapezium radiating patch and ground plane to create dual band-notch features of the antenna. This antenna provides a uniform gain with established Omni-directional radiation patterns over the entire frequency band of 3.1GHz to 10.6 GHz. The average group delay provided by the antenna is of the order of 1 ns over the UWB band and the VSWR lower than 2 (S11
