摘要： A MIMO antenna includes a plurality of antenna elements respectively including a plurality of conductive elements that are connected to different feeding points from each other; and one or more base members each being directly or indirectly provided at an upper edge portion of a windshield of a vehicle, the conductive elements being provided at either of the base members, wherein D/W, where “W” is a width of an open portion of a window frame at which the windshield is provided and “D” is a minimum distance between the conductive elements of the antenna elements in a direction parallel to the direction of “W”, is less than or equal to 0.35.

摘要： 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.

摘要： A laminated glass according to an embodiment of the present invention includes a first glass plate, a second glass plate, and an interlayer film held between the first glass plate and the second glass plate. When a relative dielectric constant of the first glass plate is represented by εg1; a relative dielectric constant of the second glass plate is represented by εg2; a relative dielectric constant of a first interlayer film provided in a first region of the interlayer film is represented by εm1; a reflection coefficient at an interface between the first glass plate and the first interlayer film is represented by Γ1; and a reflection coefficient at an interface between the second glass plate and the first interlayer film is represented by Γ2, the reflection coefficients Γ1 and Γ2 satisfy relations 0.0≤Γ1≤0.2 and 0.0≤Γ2≤0.2.

摘要： An antenna device is to be installed in a vehicle. The antenna device includes a first element; a second element; and a feeding part. An angle formed between an electric field plane generated at the first element and the second element and a direction of a long side of the vehicle is within a range of ±45 degrees.
