Abstract
This paper proposed an RF (Radio Frequency) MEMS (Micro Electro Mechanical systems) cantilever beam switch for S band application. The switch shows good RF parameters over the range of (2-6) GHz along with low actuation voltage. Although RF MEMS switches are very good counterpart for solid state switches but its high actuation voltage and high switching time is matter of concern. So in this paper, we generally concentrates on reducing the high actuation voltage for that a novel design of an RF MEMS in line series cantilever beam switch was proposed and designed using the software Intellisuite 8.7v for electromechanical analysis and by EM software for RF analysis. From simulation, we get actuation voltage of (2.5V) and insertion loss of -0.2683 dB at 2.55 GHz with return loss of -16.3720 dB at 2.20 GHz and isolation loss of -29.1203 dB at 2.40 GHz.
