Abstract: The propagation of radio waves in indoor and outdoor mobile communications is improved. An electromagnetic wave reflector includes: a panel having a reflecting surface and configured to reflect a radio wave of a desired band selected from frequency bands ranging from 1 GHz to 170 GHz; and a support supporting the panel, and, in this electromagnetic wave reflector, the support has a conductive frame and a non-conductive cover that covers at least part of the frame, and the frame has a slit and a hollow, the slit receiving an end part of the panel, and the hollow being independent of the slit.

Abstract: The electromagnetic wave reflecting device includes: a reflection panel that reflects a radio wave of a desired band selected from a frequency band between 1 GHz and 170 GHz; and a frame that holds the reflection panel. The frame has a conductive portion. The reflection panel is held by the frame so that an edge of the reflection panel is not exposed to an outside of the frame. At least a part of the conductive portion of the frame is covered with a non-conductive protecting member or protective coating.

Abstract: An electromagnetic wave reflecting device includes: a reflection panel that reflects radio waves of a desired band selected from a frequency band of 1 GHz or more and 170 GHz or less, and a frame that holds the reflection panel. The reflection panel includes: a dielectric layer, a periodic conductive pattern provided on one surface of the dielectric layer, a ground layer provided on the other surface of the dielectric layer, and an adhesive layer that bonds the conductive pattern to the one surface of the dielectric layer. The adhesive layer covers an entirety of the one surface of the dielectric layer.
