せて、アンテナ特性が劣化していた。However, in the dielectric lens manufactured by the conventional injection molding method, after the injection molding, the surface of the dielectric lens quickly cools and solidifies, whereas the inside thereof cools slowly and solidifies. Therefore, so-called shrinkage (nonuniformity, distortion) occurs and it is difficult to mold it into a desired shape,
There was a difference in relative permittivity between the skin and the inside, and the skin had a higher relative permittivity than the inside. Therefore, in the dielectric antenna manufactured by the conventional manufacturing method, the antenna characteristics are deteriorated due to the reflection of radio waves or the phase difference caused by the difference in the relative permittivity.
