摘要
提出了一种具有陷波特性的UWB天线。该天线用开槽的金属片作为辐射单元,并通过对地板的开槽处理减小了尺寸。结合HFSS仿真工具,对天线结构进行理论优化并通过大量仿真对天线尺寸进行调整,设计出一种基于FR4介质的尺寸为25 mm×15 mm×1 mm的天线模型,并设计模型进行加工测量。该天线的工作频带覆盖3.1～10.6 GHz,并避免了3.5 GHzWiMAX和5.825 GHz WLAN频段,适于超宽带无线通信系统的应用.
An ultra-wideband antenna with a notched band characteristic is presented. A slotted metal ship is used as radiating element, and the slot of floor is processed to reduce the size of antenna. Combined with FSS, the antenna structure is optimized theoretically and the size of antenna is adjusted through simulations. An antenna model with 25 mm × 15 mm × 1 mm size based on FR4 media is designed and the measured model is also made. The coverage range of the designed antenna is 3.1 × 10.6 GHz, and 3.5 GHz WiMAX and 5. 825 GHz WLAN band are avoided. It is applied to ultra-wide- band wireless communication system.
