INVESTIGATION OF THE CHARACTERISTICS OF A DEPLOYABLE SPACE MIRROR ANTENNA WITH A SPARSE REFLECTING SURFACE

The article presents the results of a study characteristics space parabolic mirror with deployable reflector. A model reflector truss structure formed by two asymmetric networks tension cables is presented. Three variants sparse reflecting film are presented, differing in periodically repeating hexagonal holes different sizes. complex electrodynamic modeling radiation antenna developed truss-bearing and proposed structures reflective films, allowing to reduce mass increase reliability system, carried out. estimation frequency dependences given. Recommendations on use films for small, medium large apertures reflectors proposed.
