Abstract—TEM horn antennas for ultra wideband (UWB) y#nSk%"t"  
system applications are proposed in which offer unique r5Wkc$  
advantages by their own structure characters. To realize ultra MsSoX9A{D  
wideband and high gain operations, some antennas are designed 'bG1U`v=3  
and compared in this paper. By optimization, two classes of 6O]Xhe0d@  
antennas can both realize the same radial character, get a AV9:O{  
satisfied gain and the bandwidth is enough for practical B\NcCp`5  
operation. As the UWB antenna, the group delay time is @eA %(C  
considered specially. The simulation resu .. (kdC1,E
