Abstract: A reflector system, an active reflector, and a method of positioning an active reflector are provided, whereby dead zones can be cancelled efficiently. The reflector system includes: a first active reflector having a first reflecting surface configured to reflect, at a variable reflecting angle, radio waves transmitted from a transmitter, at least a part of the first reflecting surface being in a boundary area located at a boundary between a line-of-sight area and a non-line-of-sight area formed by one or more obstacles that block the radio waves from the transmitter; and a second active reflector having a second reflecting surface configured to reflect, at a variable reflecting angle, the radio waves from the transmitter or the radio waves reflected by the first active reflector, the second reflecting surface being provided in the non-line-of-sight area, or at least a part of the second reflecting surface being provided in the boundary area.

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.
