PROBLEM TO BE SOLVED: To set an optional frequency bandwidth even though a radome structure is a simple structure and to appropriately adjust transmission frequency bandwidth even after the radome structure is manufactured. SOLUTION: An antenna is supported on a plane plate, a radome plate is provided in the irradiation direction of the antenna, and a half-wavelength resonator is formed from the radome plate and the plane plate. Then, the radome plate includes a polarizing plate in at least a portion thereof. Consequently, transmission frequency bandwidth in the radome plate is configured so as to be adjustable by an angle provided between a polarizing direction irradiated from the antenna and a polarizing direction of the polarizing plate.
