Thesis

RF MEMS switches for wireless communication applications

The aim of the project is to study state of the a1t in the design, development and applications of RF MEMS (Micro-Electro-Mechanical Systems) devices, with primary emphases on RF MEMS switches, in the context of its imminent insertion and deployment in radio frequency (RF) and microwave wireless applications. A detailed study of the relevance of MEMS Devices for their inclusion in the various Wireless Transceiver architectures is attempted. The project also focuses on modelling RF MEMS Capacitive Shunt Switch for Wireless applications using Lumped Components Model & 3 Dimensional Full Wave Electromagnetic Simulation of the MEMS Switch in both the ON & OFF states, within a very broad range of frequencies from DC to 50 GHz. Simulated Electric field patterns & Current distribution plots in both the states of the MEMS Switch are also given. The project includes comprehensive parametric analysis, simulating the effect of various dimensional parameters of the MEMS switch on the electromagnetic performance of the device.
