Abstract :
A directive ultra-wideband (UWB) antenna exhibiting a gain of more than 7 dBi in the whole FCC UWB frequency band is presented. The excitation of the so called dipole mode on the rod is achieved by a biconical dipole. Placing this configuration in some distance to a reflector results in a flat gain curve. Besides an input reflection of better than -10 dB from 3 up to 20 GHz, this novel antenna has an excellent transient behavior over a wide azimuth angle, whereas the dimensions can be kept very compact.
