A disclosed dual antenna system includes a receiving antenna which includes a first surface orthogonal to an incident wave, the first surface being a first antenna aperture, and a transmitting antenna which includes a second surface parallel to a reflection direction which is a transmission direction, the second surface being a second antenna aperture. A portion of a structure of the transmitting antenna is shared by the receiving antenna.

Dual antenna system

A reflectarray, including: a substrate; and a plurality of patches formed on each of areas into which a principal surface of the substrate is divided, wherein the plurality of patches are formed by including a gap.

Reflectarray

A reflect array () according to the present invention includes a plurality of array elements () forming an array configured to control a direction of a reflected wave (scattered wave) by controlling a phase of the reflected wave; and a ground plane (). The ground plane () has a structure with a frequency selective function.
