摘要

高阻抗表面的特性被用来设计天线源的接地面，以获得期望的辐射方向图。表面阻抗调制和微波全息技术被用来改变地平面的表面阻抗，以达到天线系统所需的辐射方向图。地平面分别为前两个低阶模式设计。因此，为这两种模式设计的地平面的性能，然后比较其能力，以实现所需的辐射方向图。

Antenna beam forming using holographic artificial impedance surface

The properties of the High Impedance Surfaces are used to design a ground plane for an antenna source to obtain a desired radiation pattern. Surface impedance modulation and microwave holography techniques are used to vary the surface impedance of the ground plane in a systematic pattern to achieve the desired radiation pattern for the antenna system. The ground planes are designed separately for the first two lower order modes. The performance of the ground planes thus designed for both the modes are then compared in terms of their capability to achieve the desired radiation pattern.
