Abstract: A reflect array that sets a reflection angle of a radio wave to an angle that is different from an angle of specular reflection. The reflect array includes a plurality of cells arranged in an array. Each of the plurality of cells includes at least two main resonant elements and a parasitic resonant element coupled to the at least two main resonant elements. The parasitic resonant element is configured to adjust a resonant frequency of the parasitic resonant element and adjust a reflection phase of a surface of the reflect array by adjusting a resonant frequency of the at least two main resonant elements each adjacent to the parasitic resonant element, to which the parasitic resonant element is coupled.

Abstract: An antenna includes an antenna conductor to be provided on an exterior side of a chassis and a flexible substrate. The flexible substrate includes a first insulating portion that is a portion of a sheet-shaped dielectric where the sheet-shaped dielectric is folded, a grounding conductor provided between the first insulating portion and the chassis, a second insulating portion that is a portion of the sheet-shaped dielectric where the sheet-shaped dielectric is not folded, and a signal line configured to feed power to the antenna conductor. A thickness of the first insulating portion is greater than a thickness of the second insulating portion.

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 Ag 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.
