The invention discloses a self-adaptive telescopic deployable antenna mechanism based on a rhombic bottom pentahedron and an expansion mechanism. The self-adaptive telescopic deployable antenna mechanism comprises a basic module A and a basic module B, wherein the basic module A consists of three regular dodecagonal joints, six follow-up swing rods, six spring telescopic rods, seven regular hexagonal joints, nine groups of bottom end synchronous folding connecting rods, nine bottom end gland plates, three top end gland plates and three groups of top end folding connecting rods; each of the basic modules A, B and C is a pentahedron of which the bottom surface is rhombic and four edges are converged at one point, and the positions of the conic tops of the three pentahedrons are the positions of three regular dodecagon joints; the positions of the three pentahedron cone bottom vertexes are the positions of the seven regular hexagon joints, and the top end plane and the bottom end plane are parallel to each other; any two adjacent basic modules share two regular hexagonal joints, one group of bottom end synchronous folding connecting rods and one bottom end gland plate. The invention has the characteristics of good unfolding performance, high reliability, telescopic adjustability, stable folding movement, easy expansion between modules and the like.
