Abstract

A vehicle comprises: vehicular glass including a transparent region and an opaque region; a transparent dielectric substrate disposed in the transparent region of the vehicular glass; a first area including an antenna on one side surface of the transparent dielectric substrate; and a second area including a power supply pattern and a ground conductive pattern electrically connected to the antenna. The antenna may comprise: a first slot formed between a signal pattern and a first ground pattern and configured to radiate a first signal having a circularly polarized wave in a first frequency band; and a second slot formed between the first ground pattern and a second ground pattern and configured to radiate a second signal having a circularly polarized wave in a second frequency band lower than the first frequency band.
