As a result of the unpredictable nature extreme environments (including temperature, humidity, impact, and other factors), micro-electro-mechanical systems (MEMS) solid-state fuze control modules have an urgent requirement for MEMS switch (MEMS-S3). In particular, this must remain stable without any energy input after state transition (i.e., it be bistable). paper, bistable (MEMS-bS3) is design...

This paper is focused on the creation of an efficient electromagnetic model of MEMS switches which operates at microwave frequencies. The switches are first characterized using a full wave analysis based on finite element method aiming to extract the S-parameters of the switches for different geometrical dimensions. From the S-parameter data base, a scalable lumped circuit model is extracted to...

The K-band microelectromechanical systems (MEMS) tunable band-pass filter, with a wide-frequency tunable range and miniature size, is able to fulfill the requirements of the multiband satellite communication systems. A novel 21.69–24.36 GHz MEMS tunable band-pass filter is designed, analyzed, fabricated and measured. This paper also designs and analyzes an inductively tuned slow-wave resonator,...

In the current communications market, there exists a great demand for devices, which function as passive signal processing units. High performance and small size are identified to be the bottlenecks to meet market demand in communications area[1,3]. MEMS or micromachining technology can yield small, low weight and high performance components to replace the currently used off-chip components. Th...

We propose a novel multifunctional reconfigurable antenna (MRA) design using micro/nanoelectromechanical system (M/NEMS) switches. This single MRA operates over five frequency bands of GSM900, GPS1575, GSM1800, PCS1900 and UMTS2100. The reconfigurability in operating frequency is achieved by the activation of M/NEMS switches which are integrated with the antenna architecture. Summary of Researc...

This paper presents the design of a MEMS capacitive vibration-to-electricity energy converter with integrated mechanical switches for precise timing control. Integrated lateral mechanical contact switches have the advantage of zero leakage current, low energy consumption and synchronous operation. The new design can provide an output power of 31μW at a 40V output voltage from the targeted vibra...
