摘要
设计了一种超宽带陷波天线。采用共面波导馈电的T型结构,实现了无线通信所需的3GHz-10.6GHz的超宽带带宽。通过在矩形天线贴片上开C型槽的方式,得到了在5.15GHz-5.825GHz陷波特性,避免了WLAN的干扰。同时天线结构紧凑,尺寸仅为32mm×28mm×1.6mm。仿真结果表明,天线在工作频段具有良好性能和辐射方向性。
A compact ultrawideband(UWB) antenna with extended band-notched designs is proposed.The T-shaped structure of coplanar waveguide is used to realize the ultra-wideband bandwidth of 3GHz-10.6GHz required for wireless communication.By cutting ‘C' shape on the rectangular antenna patch,5.15GHz-5.825 GHz band-notched character is obtained, to avoid the interference of WLAN.Meanwhile,the proposed antenna has a compact volume of 32mm×28mm×1.6mm.The simulation results show that the antenna has good performance and radiation direction in the working frequency band.
