摘要
本文得到了薄介质覆盖无限长导电圆柱上缝隙辐射的高频渐近结果,它以GTD的简洁形式表示,并在过渡区连续。本文利用GTD解,计算了归一化方向图,讨论了介质层厚度及介电系数ε_r的影响。本文解与精确解吻合好,计算速度迅速。
The high frequency solution of radiation from slot on an infinite long, thin dielectric coated circular cylinder is obtained. It is expressed in simple GTD form and is continuous across the shadow boundary transition region. The normalized patterns are calculated via GTD solution. The effects of the dielectric coating thickness and dielectric constant εr are studied. The solutions given in this paper agree with those obtained from exact solution very well, and the calculations can be obtained at a high speed.
