You can use a lookup table for the vertex colors possibly… three.js examples As for the geometry itself it depends what form your source data for the shape is in… Could you provide more information on this?

To make plausible antenna radiation patterns you need to have the corresponding data that affect the shape. Once you have them, the rest is just to manipulate the vertices and their colors in the geometry. Apart from ParametricGeometry, you may use other geometries too. Here is one fake Q&D pattern …

That screenshot tells not that much.
Maybe this topic will be helpful/useful somehow: Three.js implements the surface of plot? - #15 by prisoner849
