设计了一种采用微带馈电的平面超宽带天线,并在该超宽带天线的基础上,通过在微带馈线的旁边加载 U 形寄生单元的方式,在3.1~10.6 GHz 的通带内实现了3个频段的带陷特性。该天线采用 Rogers RT/duroid 5880为基板,整体尺寸仅为23 mm×13 mm×0.508 mm,具有易加工、便于集成的特点。仿真和测试结果表明该天线在3.25~3.6 GHz,5.1~5.9 GHz和9.5~9.9 GHz 处形成3个陷波频段,适合于超宽带系统的使用。

A planar ultra?wideband(UWB)antenna with microstrip feed was designed. And on the basis of the UWB antenna, the U?shaped parasitic element is added on the side of the microtrip feeder to obtain the band?notched function for the 3 notched bands. The overall dimension for the proposed antenna is 23 mm× 13 mm × 0.508 mm. Rogers RT/duroid 5880 is taken as a substrate in the system. The antenna is easy to build and integrate. Simulated and Measured results confirm that the proposed antenna forms three trapped wave bands at 3.25~3.6 GHz,5.1~5.9 GHz and 9.5~9.9 GHz,and is suitable for UWB applications.
