一种新型平面结构的双陷波超宽带天线设计
Design of a Dual Band-notched UWB Antenna with Novel Planar Structure
摘要
Abstract
To avoid interference from existing narrowband communication systems, an ultra wideband ( UWB) antenna with dual band-notched function is proposed. The modified base antenna structure has a wide impedance matching characteristic because of gradual stepped impedance feeder. The proposed anten-na realizes dual band-notched function for UWB antenna by combining two biased T-shaped parasitic ele-ments in the rear side with a window aperture on the radiation patch. The antenna current distributions re-flect resonant suppression of the two methods. Besides, the experimental results demonstrate that the pro-posed antenna prevents signal interference from WLAN (5. 15 ~5. 825 GHz) and WiMAX (3. 4 ~3. 69 GHz) effectively. However it has better omnidirectional radiation patterns in working frequencies.关键词
