Abstract
According to an aspect of the present invention, an antenna system comprises: an antenna panel ( ) which has fine irregularities ( ) on front and back surfaces thereof, the fine irregularities ( ) being formed by blasting so as to regularly reflect service radio waves having longer wavelength than sunlight and scatter sunlight. Further, according to another aspect of the present invention, a method for manufacturing an antenna system in which an antenna panel ( ) is manufactured by combining a plurality of constituent parts, comprises the steps of: finishing front and back surface portions of each of the constituent parts so as to thin down the thickness of constituent parts; blasting the front and back surface portions of the constituent parts with abrasive grains; combining the plurality of constituent parts subjected to the blasting step so as to form the antenna panel ( ) into a desired shape; and attaching an assistant reflecting mirror ( ) to the antenna panel ( ) acting as a main reflecting mirror.
