With the development of multifunctional satellites, the integration and multiplexing of satellite resources become increasingly important. Large‐scale radio‐frequency microelectromechanical system (RF MEMS) switch matrix technology is one of the key technologies to design a multifunctional satellite. This study proposed a novel sequential rotation crossbar (SR‐Crossbar) topology for large‐scale RF MEMS switch matrices. A specifically designed novel configuration scheme or arraying method for SR‐Crossbar topology is also proposed. The number of switch elements in the SR‐Crossbar RF MEMS switch matrix is significantly reduced; hence, the reliability and performance of the matrix can be improved simultaneously. For an N × N RF MEMS switch matrix, in a fully configured scenario, the maximum number of switch elements in all the paths are N ( N + 1 ) / 2 . When N ≥ 4 , the proposed SR‐Crossbar RF MEMS switch matrix topology is better than the planar Benes topology, which is already an optimised planar switch matrix topology with the minimum number of nodes.
