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 dimming laminate (10) includes: a dimming substrate (18) in which a dimming function material (16) is provided between two first transparent substrates (12) and (14); and a second transparent substrate (22) that is bonded to one first transparent substrate (12) through an adhesive layer (20). Each of the first transparent substrates (12) and (14) has a different average thermal expansion coefficient at 50-350° C. from that of the second transparent substrate (22). In the dimming laminate (10), a third transparent substrate (26) is bonded to the other first transparent substrate (14) through an adhesive layer (24), and an average thermal expansion coefficient at 50-350° C. is equal between the third transparent substrate (26) and the second transparent substrate (22).
