单个互补金属开口谐振环双陷波超宽带天线

摘要

A swallow-tailed planar ultra-wideband antenna with dual band-notched characteristics realized by complementary split-ring resonator(CSRR) was proposed for that UWB system was liable to be interfered with the narrow-band signals. Compared with the antenna reported, this method used only a single CSRR instead of two of which and realized the dual band-notched characteristics of the swallow-tailed UWB antenna, which simplified the complexity of the design and easy to be fabricated. The proposed antenna was fabricated and measured,and the measuring result was in good agreement with the simulation results.%针对超宽带系统易受窄带信号干扰的问题,提出基于互补金属开口谐振环实现的双陷波燕尾形平面超宽带天线.与以往的双陷波超宽带天线相比,该方法仅用单个互补金属开口谐振环同样实现了燕尾形超宽带天线的双陷波特性,简化了设计的复杂性,易于加工.对所设计的超宽带天线进行了制作和测量,实测结果与仿真结果吻合较好.
