| 摘 要： |
The development of new communication technologies requires new directive antenna systems to improve efficiency and security. In this work, a dielectric ring based on a graded-index permittivity profile is proposed. It consists of six lens elements homogeneously distributed over the equatorial plane of an electric dipole, which acts as feed, and converts the electric field radiated by the latter in a multibeam radiation pattern, consisting of six directive beams equally spaced as the lenses. The antenna defines a set of stable communication channels in space, by isolating the other directions in order to minimize interferences and undesired interceptions.
新型通信技术的发展需要新的定向天线系统以提高效率和安全性。本文提出了一种基于梯度折射率介电环的天线，其由六个均匀分布于偶极子赤道平面上的透镜元件组成，该偶极子作为馈源，将由其辐射出的电场转换为多束辐射模式，这些方向与透镜间距相等，形成六束定向波束。该天线通过隔离其他方向来定义一组稳定的通信信道，从而最小化干扰和不必要的拦截。 |
