Abstract: The present invention generally relates to cellular phones having multiple antennas. The invention relates to how two antennas in a diversity or MIMO antenna system interact through mutual coupling. The mutual coupling is due to proximity of the two antennas, their antenna pattern and efficiency. The performance of the system can be optimized by adjusting the mutual coupling between the antennas. The primary and secondary antennas can be "tuned" and "de-tuned" respectively to enhance system performance. In this invention, the primary and secondary antennas are tuned independently using MEMS capacitor configured in the antenna aperture for frequency tuning.

Abstract: The present disclosure generally relates to the combination of MEMS intrinsic technology with specifically designed solid state ESD protection circuits in state of the art solid state technology for RF applications. Using ESD protection in MEMS devices has some level of complexity in the integration which can be seen by some as a disadvantage. However, the net benefits in the level of overall performance for insertion loss, isolation and linearity outweighs the disadvantages.

Abstract: The present invention generally relates to a MEMS DVC utilizing one or more MIM capacitors. The MIM capacitor may be disposed between the MEMS device and the RF pad or the MIM capacitor may be integrated into the MEMS device itself. The MIM capacitor ensures that a low resistance for the MEMS DVC is achieved.

Abstract: The present invention generally relates to a MEMS device having a plurality of cantilevers that are coupled together in an anchor region and/or by legs that are coupled in a center area of the cantilever. The legs ensure that each cantilever can move/release from above the RF electrode at the same voltage. The anchor region coupling matches the mechanical stiffness in all sections of the cantilever so that all of the cantilevers move together.

Abstract: The present invention generally relates to an architecture for isolating an RF MEMS device from a substrate and driving circuit, series and shunt DVC die architectures, and smaller MEMS arrays for high frequency communications. The semiconductor device has one or more cells with a plurality of MEMS devices therein. The MEMS device operates by applying an electrical bias to either a pull-up electrode or a pull-down electrode to move a switching element of the MEMS device between a first position spaced a first distance from an RF electrode and a second position spaced a second distance different than the first distance from the RF electrode. The pull-up and/or pull-off electrode may be coupled to a resistor to isolate the MEMS device from the substrate.
