Abstract :
A new UWB antenna in bow-tie-type has been designed and implemented by utilizing the new ultra-wideband balun. In order to reduce antenna size, the balun is bended without sacrificing the balun performance. The fabricated antenna provides the operating frequency ranges from 3.2 to 11.2 GHz covering for the whole UWB frequency. The antenna maintains gains from 2.5 - 4.9 dBi for the operating frequencies with quasi- omni directional radiation patterns.
