1. An antenna device based on a transparent substrate, comprising:
a transparent substrate comprising a first surface and a second surface opposite to the first surface;
a first dielectric layer comprising a third surface and a fourth surface opposite to the third surface, wherein the first dielectric layer is in contact with the first surface via the third surface to be disposed on the transparent substrate, wherein a permittivity of the first dielectric layer is less than a permittivity of the transparent substrate;
an antenna comprising a radiation part, wherein the radiation part is disposed on one of the second surface and the fourth surface; and
an anti-reflection layer covering the transparent substrate, the first dielectric layer, and the antenna, wherein a first refractive index of the anti-reflection layer is less than a second refractive index of the transparent substrate.
