摘要： An antenna system includes a glass plate having a thickness of 1.1 mm or more and having a dielectric loss tangent of 0.005 or more at 28 GHz, and an antenna located away from one of surfaces of the glass plate, wherein a ratio of electric power radiated from the antenna to electric power input into the antenna is defined as a radiation efficiency, and wherein where an effective wavelength of an electromagnetic wave at a predetermined frequency that is 10 GHz or more is denoted as Ag, and where the radiation efficiency is denoted as η 0 [dB] when the glass plate and the antenna are in contact with each other, and is denoted as η λg/2 [dB] when a distance between the one of the surfaces and the antenna is λg/2, the glass plate and the antenna are arranged so as to obtain the radiation efficiency of η A [dB] that satisfies η A ≥ η 0 + (η λg/2 - η 0 ) × 0.1.
