PROBLEM TO BE SOLVED: To provide an antenna that is provided with a sheet radome and has an excellent radio wave characteristic. SOLUTION: The antenna is provided with a tension component (1) fitted to a sub reflection mirror (5). The tension component (1) pushes a middle part of the sheet radome (2) in a front direction of the antenna from an opening end of a shroud (3) to allow the sheet radome (2) to take a conical shape. The outer circumferential part of the sheet radome (2) is fixed to the shroud (3) without applying any tension to the sheet radome (2) and thereafter a feeding part (6) and the tension component (1) are fitted to push out the sheet radome (2). Thus, the face of the sheet radome (2) forms the conical shape not perpendicular in a radio wave radiation direction and a tension can be provided to the sheet radome (2) at the same time.
