摘　　要：提出了一种微带馈电的新型超宽频的天线,该天线印刷在覆铜介质基板上,介质基板尺寸为30.0mm×35.0mm×1.6mm,材料是介电常数为4.4的FR4介质,利用仿真软件HFSS对天线参数进行仿真和优化。通过在微带面上开缝,可实现天线频带宽度(回波损耗S11<-10dB)2.6～11.5GHz,相对带宽达126%。结果表明,该设计天线不仅满足超宽带要求,且结构简单,体积小,适合在超宽带天线(UWB)通信中应用。A novel microstrip-fed ultra-wideband antenna is proposed in this paper. The antenna was etched on a copper-cladding substrate. The size of the substrate is 30 mm× 35 min× 1.6 mm and the substrate material uses FR4 with relative permittivity of 4.4. The antenna parameters have been simulated and optimized by using the simulation software HFSS. The bandwidth （return loss≤-10 dB） starts from 2.6 GHz up to 11.5 GHz that means a relative bandwidth of 126% by slotting on the surface of microstrip. The results show that the designed antenna not only re- alizes UWB but also is simple in structure, small in size and suitable for UWB communications.
