| 摘 要： | 为克服无线通信中系统间的相互干扰,采用频带抑制技术设计了一种具有双阻带特性的超宽带单极子天线。首先采用共面波导进行馈电,辐射贴片和共面波导均为阶梯结构,使其在2.9～12GHz频带内电压驻波比小于2;其次在辐射贴片上分别引入C形和倒U形槽谐振结构,使其在3.3～3.9GHz和5.1～5.9GHz的频带内电压驻波比大于2;最后通过仿真与测量,验证该天线实现了良好的频带抑制功能。

| Abstract: | In wireless communication systems, in order to overcome the mutual interference between systems, anUWB monopole antenna with dual band notched characteristic is proposed using band suppressed technology. Firstly, a step structure radiation patch which is fed by CPW is designed to obtain the voltage standing wave ratio (VSWR) less than 2 infrequency band 2. 9 ~12GHZ. Secondly, C shape and pour U shape resonant slots are introduced separately on the radiationpatch to obtain band notched characteristic. After optimization, the simulation results show that the VSWR of the antenna hasgreater than 2 value in 3. 3 ~3. 9GHz and 5. 1 ~ 5. 9GHz frequency band. Finally, the antenna was fabricated and tested.The simulation and measurement result show that they matched very well and demonstrated that the frequency band sup pressed function of the antenna is well achieved. |
