提出了具有良好带阻特性的小型微带螺旋缺陷谐振单元,通过软件仿真分析说明了参数变化对结构电磁特性的影响;利用5个单元级联的传输线取代传统微带天线的50Ω馈线,设计了具有谐波抑制功能的微带天线。实验结果表明:5个单元级联的传输线能够在不改变传统天线有效面积、基模频率和天线方向图的前提下可以有效的抑制天线的4次谐波。提出的天线结构是单平面的,不仅易于加工,而且便于实际应用。

A compact microstrip spiral-defected resonant cell with good rejection characteristic was proposed,and its electromagnetic characterizations were investigated by using HFSS. Replaced the 50 Ω feed line with a five series-wound cell transmission line,an antenna with good capability of suppression harmonic was designed. Simulation and measurement results indicate that the proposed antenna can suppress four harmonics at upper bands as the effective size,basic mode and radiation pattern keeping. The designed antenna characters with uniplanar,simple fabrication and practical using.
