TRANSPARENT ANTENNA, ANTENNA ARRAY, AND DISPLAY MODULE

A transparent antenna includes a transparent base; and a metal thin wire layer on an upper side of the transparent base. A transparent base has a thickness of 300 µm or less. The metal thin wire layer has an opening ratio of 80% or more. When an input reflection coefficient S11 at a frequency of f [GHz] and a radiation efficiency are denoted by S11(ρ, f) and Eff(p, f) [%], respectively, in a state where a metal conductor having a surface resistivity ρ [Ω/sq] is placed parallel to the antenna 0.15 mm apart, at two frequencies f1, f2, which are between 2 GHz < f < 50 GHz, relationsS11(0.1 [Ω/sq], f1[GHz]) < -3 [dB],S11(0.1 [Ω/sq], f2[GHz]) < -3 [dB], and|Eff(0.1 [Ω/sq], f1 [GHz]) - Eff(0.1 [Ω/sq], f2 [GHz])| < 25%are satisfied.
