PROBLEM TO BE SOLVED: To obtain a multi-frequency band common use antenna system that has a desired electric field strength distribution even at a low frequency band. SOLUTION: In this multi-frequency band common use antenna system consisting of a main reflecting mirror 1, a frequency selection mirror surface 2 consisting of a dielectrical body 3a and a resonator element 8 placed on the dielectric body 3a and comprising a plurality of metallic foils, a high frequency band use primary radiator 4 placed in front of the frequency selection mirror surface 2, and a low frequency band use primary radiator 5 placed on a rear face of the frequency selection mirror surface 2, the dielectric body 3 is formed to be a lens. Furthermore, a plurality of low-frequency band use primary radiator 5 are arranged to be an array. Moreover, the main reflecting mirror 1 and the frequency selection mirror surface 2 are used for correction mirror surfaces.
