A new design of compact microstrip?fed ultrawideband(UWB)antenna is presented,whose total size is 30 mm× 30 mm. The antenna consists of a Y?shaped radiating patch,a pair of“8”?shaped resonance chips and a grounding plane with a rectangular slot. The 3?D electromagnetic simulation software is applied to simulating the parameters such as return loss,gain and radiation pattern of the antenna. Simulated results show that the antenna′s frequency band range is 3.06~13.98 GHz,whose voltage standing wave ratio(VSWR)is less than 2,which can provide a wide usable bandwidth of 10.83 GHz. The antenna re?veals a good omni?directional radiation characteristic. The antenna configuration is simple,easy to fabricate,and can be integrated into UWB systems.
