提出了一种具有单陷波特征的可重构单极超宽带天线。所提出的超宽带天线工作在3.2 GHz至12 GHz频段。陷波频带是通过结合在辐射片上蚀刻的开关弯曲槽来实现的。采用射频MEMS系列开关实现切换重构，减少对3.3 GHz ~ 3.9 GHz WiMAX频段主要用户的干扰。该结构有两种模式，由射频MEMS开关控制。所提出的超宽带天线在3.1 ~ 12 GHz范围内实现（VSWR < 2）。并给出了不同频率下的模拟辐射方向图和电流分布。仿真结果表明，该天线适用于认知无线电应用。
Reconfigurable monopole UWB antenna with single notched features is presented. The proposed UWB antenna operates at frequency band from 3.2 GHz to 12 GHz. The notched frequency band is accomplished by combining switched meandered slot etched in the radiating patch. The switching reconfiguration is achieved by using RF MEMS series switch to reduce the interference to the primary users operating in WiMAX bands from 3.3 GHz to 3.9 GHz. The structure has two modes which are controlled by the RF MEMS switch. The proposed UWB antenna achieves (VSWR < 2) from 3.1 to 12 GHz. Also, the simulated radiation pattern and current distribution at different frequencies are presented. The simulated results confirm the antenna is suitable for cognitive radio applications.
