| 摘 要： | 研究了3种典型EBG结构在曲面上表面波带隙特性,利用悬置微带线法,分析了曲面EBG结构带隙特性与其结构参数及曲率的关系。结果表明,曲率对表面波带隙的影响不是太明显,只是带隙中心频率有稍微的下降,介电常数与介质厚度对带隙影响规律与平面上一致。这一结论对在圆柱共形天线上应用高阻表面结构有一定的指导意义。

| Abstract: | The surface wave band-gap characteristics for three typical curved EBG structures are studied in this paper.Using the suspending micro-strip method,the effect of curved EBG structure parameters and curvature on band-gap characteristics is analyzed.The results show that the effect of curvature is lesser,and only the center frequency of band-gap is slight decreased. The effect of substrate permittivity and dielectric thickness on band-gap characteristics is in agreement with that of the planar structure parameters.This conclusion is of certain guided significance in applying such kind of surface structures to cylindrical conformal antennas. |
