Abstract
The bi spectral window is made of dielectric material with a low loss factor and high dielectric constant. The window has rotation symmetrical, aspherical front and rear surfaces. The front surface is arranged on the side of the reflector on which the millimeter wave radiation is incident, and is optimally matched to the reflector surface. The rear surface is designed for optimal millimeter wave reflectivity. An Independent claim is also included for a reflector antenna.
