design an antenna in HFSS

I have to design two antennas . For that i have two base paper also. These two antennas have a bandwidth in the UWB range and three notched bands for WLAN, WiMAX and downlink Satellite Communication. So, first simulate the orginal paper output. Then i need a modification to the paper including one antenna can be extended to GSM and another antenna to cover Bluetooth at the same time , orginal output also there.
