摘要:

介绍了太赫兹频段引信天线的优缺点与背景需求。为实现太赫兹频段引信天线工程应用，分析了介质透镜天线在太赫兹频段的工作原理及应用特点，采用H面喇叭嵌装介质透镜天线形成太赫兹频段引信天线，可以有效缩短H面喇叭天线的纵向尺寸。并利用透镜的偏焦技术形成不同波束倾角的引信天线，对不同波束倾角的太赫兹引信天线进行了仿真计算，仿真计算结果验证了该技术方案的可行性。

Abstract:

The background requirements of the fuze antenna in terahertz spectrum as well as its advantages and disadvantages are introduced. The working principles and application characteristics of dielectric lens antenna in terahertz frequency are analyzed in order to implement the terahertz fuze antenna. The longitudinal size of H plane horn antenna can be reduced effectively by using fuze antenna formed by an H plane horn with dielectric lens antenna. The terahertz fuze antenna with different beam angles is achieved by focal technology of lens. The feasibility of the technology solution is verified through simulation.
