中文摘要： 近年来，动态海水天线已成为一个有趣的研究课题。该种天线主要由一个馈电结构和一段由水泵喷射形成的水流构成。它具有实时和可重构的优点，但是，效率低下一直是制约其发展的重要因素。. 本课题组在高效率静态海水天线领域已经作出了一些重要的贡献，但是如何设计高效率动态海水天线仍然是一个充满挑战的难题。因此在前期研究的基础上，我们将首先设计一个适合于动态海水天线的高效率馈电结构。接着，建立动态海水天线的理论模型，从理论上分析各个参数对天线性能的影响，从而得到一个高效率动态海水天线的有效设计方法。最后，我们将设计一些高效率的动态海水天线及天线阵列，并对它们进行加工和测量。

英文摘要： In recent years, dynamic sea-water antenna was becoming an interesting research topic, which mainly consists of a feeding structure and a sea-water stream supplied by a pump. It has the advantages of real-time and re-configurability. However, the problem of low efficiency is still an important factor restricting its application.. Our research team had made some important contributions in the area of high-efficiency static sea-water antenna, but how to design a high-efficiency dynamic sea-water antenna is still a challenge problem. Therefore, base on the previous studies, we will first design an efficient feeding structure， which is well suitable for dynamic sea-water antenna. Then, a theoretical model of the dynamic sea-water antenna will be build, which can be used to analyze the effect of various parameters on the antenna performance, thus providing an effective design approach for high-efficiency dynamic sea-water antenna. Finally, some high-efficiency dynamic sea-water antenna and antenna arrays will be designed, fabricated and measured.
