摘　　要：用改进微扰法分析了任意曲线形状圆柱形介质栅全向天线的辐射特性.文中选取了几种介质栅形状漏波天线进行研究,并对它们的辐射特性进行了比较分析;所得结论对该类全向漏波天线的设计具有实际意义.Characteristics of omni-directional dielectric rod grating leaky antennas with arbitrary profiles are investigated by an improved perturbation method. Leaky wave antennas with specific profiles are analyzed and their radiation properties are compared; the conclusions based on the present analysis are of practical significance for the design of these kinds of leaky wave antennas.
