A compact novel printed CPW-fed antenna for super-wideband (SWB) application is presented. Modifying the circular disc radiating patch to dome shape and by cutting the lower edges of the radiating patch in the form of rectangular staircase shape the super-wideband is achieved. The proposed antenna has a compact size in its structure compared to conventional antenna designed for the same frequency. The proposed SWB antenna has compact in its size of 26 × 32× 1.6 mm3 fed by CPW and gives an impedance bandwidth of more than 171% (2.70-32.79 GHz) for |S11|< -10 dB and exhibits an omnidirectional radiation characteristics over the entire frequency band and with an moderate gain. The design of the proposed antenna and its various parameters are studied by using the Ansys HFSS software. The present antenna may cover the personal wireless communication services such as Bluetooth (2.8 GHz), WIMAX (3.4 GHz), WLAN (2.4/5 GHz), UMTS and Ultra-wideband (UWB)(3.1- 10.6 GHz) applications.
