Currently, large deployable antennas are utilized onboard spacecraft for satellite communications, remote sensing, and VLBI applications. These antennas often use knitted wire mesh as a reflecting surface because it is lightweight and demonstrates an elastic behavior due to its knitted structure, which allows improved packaging surface has high reflectivity with the electric field parallel to

When communication satellite is launched into the space around the earth orbit, it urgently needs to reduce weight to cut down cost. At the same time, large deployable mesh antenna, which is mainly woven by wires, possesses several advantages such as lightweight, elasticity and deployable so as to reduce the packaging features during launch. Mesh
