摘要
全息天线是一种利用全息结构改变源天线辐射特性,得到目标辐射特性的口径天线。全息结构为平面结构,源天线的工作频率以及目标天线的辐射方向决定全息图案的结构。本文从全息天线的理论出发,利用喇叭天线作为馈源,采用Ansoft HFSS对不同张角的全息基板进行仿真,发现随着全息基板张角的增大,全息天线的辐射效率先增大后减小,存在一个最大值,此时全息天线辐射效率最高。采用此全息基板的张角,不仅能够实现全息天线的小型化,同时提高了全息天线的辐射效率。
Holographic antenna which uses the holographic structure to change the characteristic of source antenna radiation is a aperture antennas of achieving the characteristics of target radia‐tion. The holographic structure is a planar structure as well as the operating frequency of the source antenna and the radiation direction of the target antenna determine the structure of the holographic pattern. Based on the theory of holographic antenna, this paper, by adopting horn antenna as the feed source, uses Ansoft HFSS to simulate the holographic substrate with different substrate angle. When the angle of the holographic antenna increases, the radiation efficiency of the holographic antenna increases first and then decreases. The holographic antenna radiation efficiency is the highest when the radiation efficiency comes to the maximum. The interception part of the holographic antenna not only reaches for its miniaturization, but also improves its ra‐diation efficiency.
