【摘要】：设计了一款工作在太赫兹频段的开槽介质型菲涅尔(Fresnel)透镜天线,该天线由馈电结构和透镜结构两部分组成。利用CST微波仿真软件,首先设计波纹喇叭馈电结构,其次基于波纹喇叭馈电结构设计开槽型菲涅尔透镜天线,分析全波周期、焦径比和子区等对天线性能的影响,通过横向和纵向对比,确定最佳天线参数。结果表明对天线性能影响从大到小分别为:焦径比、全波周期、子区。焦径比F/D=3、全波周期w=3、子区P=4为最佳天线参数,波纹喇叭馈电天线经过开槽介质型菲涅尔透镜天线聚焦后,天线的增益提升12.5 d B。
[Abstract]:A slotted dielectric Finel (Fresnel) lens antenna is designed in the terahertz band. The antenna is composed of two parts: the feed structure and the lens structure. Using CST microwave simulation software, the first design of corrugated horn feed structure, followed by corrugated horn feed structure design of slotted type Fresnel lens antenna based on the analysis of influence of full wave cycle, the focal diameter ratio and sub area on the performance of the antenna, through horizontal and vertical comparison, determine the optimum antenna parameters. The results show that the effects of the antenna on the performance of the antenna are as follows: the ratio of the focal diameter, the full wave period and the subregion. The optimum antenna parameters are the focal diameter ratio F/D=3, the full wave period w=3 and the sub area P=4. After the focusing of the corrugated horn feed antenna through the slot dielectric Finel lens antenna, the gain of the antenna is increased by 12.5 D B.
