To meet the requirements for larger aperture and high storage rate deployable antenna in the space missions, a geometry modeling design scheme for parabolic cylindrical antenna was proposed based on module connection. The scheme raised in this paper realized geometry modeling for different aperture of antenna utilizing several kinds of modules. According to the shape feature of mesh surface of the parabolic cylindrical antenna, the schematic design for module division was carried out in the parabolic direction and baseline. The number of modules and the size of links were calculated meanwhile. The validity of the scheme was proved by numerical analysis for the deployable process.
