Abstract: An antenna device includes an array antenna configured to radiate a radio wave. The array antenna includes at least four radiating elements arranged substantially parallel to a beam scanning plane of the radio wave. The at least four radiating elements are arranged substantially parallel to a first principal surface of window glass for a building, with the antenna device arranged such that the array antenna is arranged at the first principal surface of the window glass in a non-contact manner and such that the radio wave is radiated toward a second principal surface of the window glass opposite from the first principal surface.

Abstract: A transparent antenna includes a transparent substrate; and a metal thin wire layer on an upper side of the transparent substrate. The transparent substrate has a thickness of 300 μm or less. The metal thin wire layer has an opening ratio of 80% or more. When a metal conductor having a surface resistivity ρ Ω/sq is placed parallel to the transparent antenna 0.15 mm apart, an input reflection coefficient S11(ρ, f) and a radiation efficiency Eff(ρ, f) at a frequency f satisfy relations S11(0.1 Ω/sq, f1 GHz)
