PROBLEM TO BE SOLVED: To provide a mesh expansion antenna with less number of components for an adjustment mechanism for adjusting a tension of a radio wave reflection mirror surface through the manufacturing using a forming die wherein prescribed precision of the radio wave reflection mirror surface can be maintained even when containing and expansion are repeated, damages of and deterioration in the radio wave reflection mirror surface hardly take place, and the radio wave reflection mirror surface can be easily replaced if the damages or deterioration is caused. SOLUTION: The mesh expansion antenna 1 includes a radio wave reflection mirror surface body 10 with a grating-like mesh reflection mirror surface 2 formed as a radio wave reflection surface of a parabolic antenna; an opening/closing mechanism 20 for expanding/containing the radio wave reflection mirror surface body; and a support 21 slidably supporting the opening/closing mechanism, and is configured such that the radio wave reflection mirror surface body includes the stainless steel made grating-like mesh reflecting mirror surface 2, a rib support part 3, and a plurality of ribs 4, and the opening/closing mechanism includes a link arm 14, a slide block 11, and a fastening means 16.
