Claims

[Scope of utility model registration request]

゛ In a reflector antenna equipped with a main reflector, a sub-reflector, and a -order radiator, the space between the main reflector and the sub-reflector is filled with a foam dielectric, and one of the upper and sub-reflectors is Alternatively, a reflector antenna characterized in that both of them are formed by coating the foamed dielectric material with a thin radio wave reflecting film.
