Abstract: A laminated glass according to the present invention includes a first glass plate, a second glass plate, and an interlayer film. The interlayer film includes a laminated region including a first layer that is in contact with the first glass plate, a second layer that is in contact with the second glass plate, and a third layer disposed between the first layer and the second layer. When the relative dielectric constant of the first glass plate is denoted by εg1, the relative dielectric constant of the second glass plate is denoted by εg2, the relative dielectric constant of the first layer is denoted by εm1, the relative dielectric constant of the second layer is denoted by εm2, and the relative dielectric constant of the third layer is denoted by εm3, relationships εm1 εm1, εm3>εm2 are established.

Abstract: An antenna system includes a glass plate having a thickness of 1.1 mm or more and 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 when an effective wavelength of an electromagnetic wave at a predetermined frequency is 10 GHz or more is denoted as λg and the radiation efficiency as η0 [dB] when the glass plate and the antenna are in contact, and is denoted as ηλg/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 to obtain the radiation efficiency of ηA [dB] that satisfies ηA≥η0+(ηλg/2−η0)×0.1.
