PURPOSE:To obtain an antenna system by covering respective reflector conductors and radiator conductors with a radome and protecting them against wind pressure, fixing those to the inside or surface of a wall body in the radome and protecting them against acceleration, and fitting parts joined with the radome side wall or ceiling in fitting structure and facilitating attachment and detachment. CONSTITUTION:The wall body 11 is made of the same material as that of the radome 6 or a dielectric with low loss to in-use wavelength in a cross shape, and reflector conductors 2-4-2-1 and 20, 21-24, and 3-4-3-1 and 31-34 are buried internally. The wall body 11 is also made of the same material and provided to the intermediate part of the wall body 11, and radiators 51-54 are embedded internally. The reflector conductors 2 and radiator conductors are covered with the radome 6 and conductor elements and wall body are united, so the conductor elements are protected from a wind pressure load and not damaged with force based upon acceleration. The radome wall can be made thin by the presence of the wall body and electric performance is improved. Further, the fitting structure is employed to join the side wall or ceiling of the radome to facilitate the attachment and detachment.
