摘要
利用仿真软件HFSS设计了一款共面波导馈电的超宽带(UWB)天线。采用开槽的方法实现了天线在WLAN(5.15GHz^5.825 GHz)和ITU卫星通信(8.025 GHz^8.4 GHz)频段的陷波特性。在介电常数为4.4的FR4介质基板上制作了天线,天线尺寸仅为22 mm×28 mm×0.8 mm,易于与其它电路集成。实测和仿真结果吻合较好。
A coplanar waveguide-fed ultra-wideband antenna is presented. The antenna is simulated using HFSS.Two notched bands of the antenna in WLAN（5.15 GHz^5.825 GHz）and satellite communication of ITU（8.025GHz^8.4 GHz）are achieved by etching U-shaped slotlines on the radiator patch and the fed microstrip conductorsline. The antenna is implemented on one substrate with relative permittivity 4.4,the whole size of the antenna is on-ly 22 mm×28 mm×0.8 mm and easy to be integrated with other circuits. There are basic agreements between thesimulated and measured results.
