Measurement of the Antenna Mesh: Characteeristics for VSOP-2/ASTRO-G

The surface of the main reflector antenna of the VSOP-2 satellite is made of metal wire that is woven into a tense mesh. Numerical simulations are required to determine the reflectivity characteristics of the mesh which are functions of the reflecting angle, polarization and frequency of the incident radio wave and the tension of the mesh. These characteristics were measured with the tension of 200g/m, 350g/m, 500g/m.
