摘　　要：设计、制备、测试一种基于聚酰亚胺基板的柔性双陷波超宽带天线。提出的天线在室温下由表面改性和原位自金属化技术制备,由该技术制备的柔性双陷波超宽带天线低于-10 dB的仿真和测试的带宽分别是2.58～10.7 GHz和2.5～10.87 GHz,实现了WiMAX频段和WLAN频段的陷波。天线在3.5 GHz和5.5 GHz两个频率都保持着良好的全向辐射特性。此外,为了确保该柔性天线的实际可操作性,还测试了不同弯曲程度下天线的性能。该技术工艺过程简单,成本低,可以作为印刷技术的替补,在柔性电子设备中有广泛的应用前景。A flexible dual band.notched ultra.wideband(UWB)antenna based on polyimide(PI)substrate is designed,fabricated and tested.The proposed UWB antenna is fabricated by surface modification and in situ self.metallization technique at room temperature.The simulated and tested bandwidth of the flexible dual band.notched UWB antenna(lower than-10 dB)fabricated by the technique is 2.58~10.7 GHz and 2.5~10.87 GHz respectively,the band.notched performance of WiMAX(3.3~3.7 GHz)and WLAN(5.15~5.825 GHz)is realized.The antenna has good omnidirectional radiation characteristic at both 3.5 GHz and 5.5 GHz.The performance of the antenna under different bending conditions is tested to ensure the practical operability of the flexible antenna.This technique has simple process and low cost,can act as the substitution of printing technology,and has broad application prospect in flexible electronic devices.
