PROBLEM TO BE SOLVED: To provide a large-sized portable antenna that consists of membrane materials, mesh materials, cable materials and connection components which interconnect them so as to attain a weight-reducing structure, while having a high containing capability thereby realizing a large-sized reflection mirror surface at a light weight with a high carrying performance. SOLUTION: In the large-sized portable antenna having a reflecting mirror surface, a cable structure 12 consists of cables, nodes that are placed on a parabolic face to connect ends of the cables, and nodes, inside of which the cables pass through. Furthermore, a reflection membrane structure section 13 fixed to the cable structure 12 configures a reflecting face for radios wave. Then a lens-shaped inflatable structure 11, fixed to the cable structure 12 at points, uniformly provides a tension to the cable structure 12 by the expansion of itself.
