徴とする周波数共用反射鏡アンテナ。 A frequency sharing reflector antenna that has a primary radiator that transmits and receives each beam in the low frequency band and high frequency band, and a reflector that reflects the radiation beam of the primary radiator in the beam forming direction, is a linear antenna with a polygonal shape. a first primary radiation part that forms a beam of low frequency and radiates the beam of the low frequency band to the reflecting mirror;
An aperture antenna having an aperture that is equal to the beam blowing angle to the reflecting mirror of the primary radiation part is arranged inside the polygon formed by the linear antenna, and the high frequency beam is directed to the reflecting mirror. The frequency sharing device is characterized in that the primary radiator is configured with a second primary radiator that radiates to the second primary radiator, and the second primary radiator is made of a material that transmits low frequencies and reflects high frequencies. reflector antenna.
