中文摘要：
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。
英文摘要：
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.
