辐射方向图
辐射方向图（radiation pattern），也称为天线方向图（antenna pattern）、远场方向图（far-field pattern），是一个在天线设计领域的术语。它是描述天线或其它信号源发出无线电波的强度与方向（角度）之间依赖关系的图形。
对于线性极化天线，常用E平面方向图（E-plane）和H平面方向图（H-plane）两个图来表示。

Radiation pattern 辐射方向图
In the field of antenna design the term radiation pattern (or antenna pattern or far-field pattern) refers to the directional (angular) dependence of the strength of the radio waves from the antenna or other source.
Particularly in the fields of fiber optics, lasers, and integrated optics, the term radiation pattern may also be used as a synonym for the near-field pattern or Fresnel pattern. This refers to the positional dependence of the electromagnetic field in the near-field, or Fresnel region of the source. The near-field pattern is most commonly defined over a plane placed in front of the source, or over a cylindrical or spherical surface enclosing it.
