摘要： An electromagnetic wave reflector includes a panel having a reflective surface that reflects a radio wave of a frequency band selected from 1 GHz to 170 GHz, and a support body that supports the panel. The support body has a connector part electrically connected to the reflective surface, the connector part being configured to propagate a reference potential of a reflection having occurred at the reflective surface.

摘要： 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.

摘要： An antenna includes a ground plane; a first resonator connected to a feeding point with reference to the ground plane; and a second resonator that is fed power by the first resonator according to an electromagnetic field coupling with no contact. The second resonator includes a first conductor part, and a second conductor part capacitively-coupled to the first conductor part through a gap. A dielectric loss tangent of a substrate part, on which the second resonator is formed, is greater than zero and less than or equal to 0.01.
