| 摘 要： | 本文用改进的微扰法分析了毫米波介质栅漏波天线的辐射特性。文中通过横向谐振法确定漏波天线的相位常数,而漏波常数的计算归结为对有源传输线方程的求解。所得数据和用场匹配方法得到的精确值进行了比较,结果表明,本文方法在保持相同精度的情况下,简化了分析和计算过程。

| Abstract: | An improved perturbation procedure is used for analysing the radiation characteristics of the millimeter wave dielectric leaky wave grating antenna. The electromagnetic fields are described in terms of a transverse transmission line network, which brings considerable physical insight into the overall behavior of the antenna. The analysis is simple and practical. Its accuracy is as high as the rigorous method. |

| Keywords: | Dielectric grating antenna Improved perturbation method Equation of transmission line with sources |
