| 摘 要： | 针对超宽带系统易受窄带信号干扰的问题,提出了一种双陷波平面超宽带天线。通过在天线的辐射贴片上加载U形槽实现了5.1～5.9GHz频段内的陷波,在接地板上引入寄生条带实现了3.4～4GHz频段内的陷波。仿真与测试显示:该天线在3～11.1GHz的频带范围内具有良好的阻抗特性、辐射方向特性,在其中3.4～4GHz和5.1～5.9GHz范围内具有双陷波特性,与相关文献相比,能够有效地抑制WiMAX和WLAN系统之间的干扰,是一种性能较好、实用价值高、能广泛应用于超宽带系统中的陷波超宽带天线。

| Abstract: | Because the UWB system was subject to be interfered by narrow-band signals,a planar ultra-wideband antenna with dual band-notched characteristics was proposed.A U-shaped slot in the radiating patch was utilized to achieve the band-notched characteristics within 5.1~5.9 GHz and the parasitic strip on earth plate was applied to realize the band-notched characteristics within 3.4~4.0 GHz.The simulated and measured results showed that the antenna with dual band-notched characteristics within the frequence range between 3.4~4.0 GHz and 5.1~5.9 GHz had good impedance characteristics and good radiation performance within 3~11.1 GHz.Compared with the correlative literature,this antenna could effectively restrain the interference between WiMAX and WLAN system and was of good performance and high practicality. |
