Patent ID: 10573479

Abstract:
A micro-electromechanical-system (MEMS) switch (1) is formed in a substrate (2) and includes a first RF signal line (3) and a second RF signal line (4), a deformable membrane (5), an activator (7) configured to deform the membrane (5), a substrate track, and a membrane track. The RF signal lines (3, 4) are connected by one of the membrane track and the substrate track. A membrane RF ground (9, 10) is integrated into the membrane (5), and the membrane RF ground is electrically connected to a substrate RF ground (11, 12, 3, 14), the membrane RF ground framing and being formed parallel to at least one among the membrane track (8) and the substrate track, such that the RF ground (9, 10) closely follows the RF signal path, in order to guide the propagation of the RF signal of the first RF signal line (3) to the second RF signal line (4) when the switch is in the on state.
