摘要：
A compact ultrawideband (UWB) antenna with 3.5/5.2 GHz band-notched characteristics is proposed. The proposed antenna is composed of a half elliptic annulus radiation element fed by microstrip line and a step-shaped ground plane with truncated corners. By inserting closed-looped resonating structure onto the radiation patch and connecting open-looped resonator on the back side with patch via metallic hole, the dual notched frequency bands are achieved. The numerical and experimental results exhibit a wide impedance bandwidth ranging from 3.08 to 11 GHz with the dual notched bands around 3.5 and 5.2 GHz. Additionally, nearly omni-directional radiation patterns, moderate gain, and small group delay variation are also obtained.
