摘　　要：提出了一种具有双陷波特性的共面波导馈电的超宽带天线。该天线的结构类似于一般的单极子天线，辐射体采用双环形结构，馈电部分由共面波导来实现，具有良好的宽带阻抗匹配特性。通过在辐射体和馈电部分分别嵌入不同形状的缝隙，使得天线在（3．2～3．6GHz和5-6GHz）出现频带阻断，并且天线在通带内呈现良好辐射的特性。A CPW fed planar ultra wideband antenna with dual band-notched characteristics was proposed. The antenna is similar in the configuration of a conventional monopole antenna. The dual-ring topology structure of radiating element and part of feeder realized by CPW that possesses a good impedance match over a broad frequency range. Inserting two different shapes slots in the radiating element and feed part, respectively. Dual band-notched characteristics of the antenna can be created within the frequency range between 3.2-3.6 GHz and 5-6 GHz. The antenna exhibits a good radiation characteristics in pass band.
