Abstract
An antenna system is provided with an antenna panel which has fine bumps and dips formed on a mirror surface side, which is one of surfaces opposing to each other, by etching, wherein the fine bumps and dips scatter sunlight entering the mirror surface side of the antenna panel to suppress the collection of the sunlight and regularly reflect radio waves having longer wavelength than the sunlight entering the mirror surface side of the antenna panel.
