PROBLEM TO BE SOLVED: To provide an antenna system capable of suppressing decreasing the amount of diffracting scattering waves and reflected waves propagated along a radome. SOLUTION: In the antenna system provided with a radiation element, a reflection mirror and the radome, a radiation electromagnetic field adjustment sheet member is placed in parallel with a slope to an outer edge of the slope of the radome. In this case, it is desirable that the inner circumference of the radiation electromagnetic field adjustment sheet member should be substantially non-circular. COPYRIGHT: (C)2003,JPO
