A controllable tri-band-notched UltraWide Band (UWB) antenna is presented to avoid the interference of services working in the UWB band such as WiMax, WLAN, and X-band satellite system applications. The tri-band-notched characteristics are achieved by etching slots on the radiating patch and the ground plane, and adding a parasitic ring unit on the back of substrate. The proposed antenna operates on the UWB (3.1~10.6 GHz) efficiently, and it can inhibit interference from three different kinds of narrow band communication systems. A switch is added on the parasitic ring unit in order to realize the conversion between dual band-notched and tri-band-notched functions. Simulated and measured results show that the proposed antenna provides excellent band-notched function on the rejectband and has nearly omnidirectional radiation patterns on the passband.
