Claims

[Scope of utility model registration request]

A metal grid is provided on a dielectric plate of a predetermined thickness in order to utilize the radio wave reflection, transmission, and polarization conversion effects of the metal grid.Furthermore, a metal grid is placed on the surface of this metal grid to reflect light waves in a predetermined wavelength range. A reflector coated with a dielectric multilayer film, a frequency selection plate that separates radio waves and light waves, a primary radiator for transmitting and receiving radio waves from the reflector, and a radar signal connected to the primary radiator. A transmitting/receiving device comprising: a transmitting/receiving device that transmits and receives; and a detector that is provided on a different axis from the primary radiator and detects light waves received by the optical system of the reflecting mirror.
