Two anchor RF switch with variable step size

The emerging trend in wireless communication devices have shaped the requirement of micro-devices having the inimitable capability of operating in the radio frequency (RF) range. RF MEMS switches have brought about a revolution in the volatile area of nanotechnology, due to its exceptional and extensive switching capability. The focus of this research is the analysis and redesign of contact type radio frequency micro-electro-mechanical system (RF MEMS) that has improved sustainability, durability and switching speed. The work includes analysis of the discrepancy in the conventional switch (pull-in voltage optimized switch). Then the switch has been redesigned geometrically and the stationary properties of the switch have been observed. Further, to improve the results, the properties have been compared for various materials and parameters. It has been observed from the simulation results that reduction in displacement is achieved and the use of metals improves the result.
