Abstract: | Design and simulations of a novel RF MEMS switch is reported as a solution to many RF wireless applications. A new comb structure
for RF MEMS switch is proposed for low voltage and high frequency operations. Isolation degree and actuation voltage, both
improved by the new structure. The mechanical and electromagnetic simulation results show better performance for this new
switch compared to parallel plate switch. The simulation is done by the intellisuit and HFSS softwares. The Simulation results
show that the actuation voltage is decreased by 13% and the linearity of the switch displacement with respect to the actuation
voltage is improved by 22% compared to the parallel plate structure. The HFSS simulation results indicate an insertion loss
better than 0.33 dB at 50 GHz and isolation greater than 13.4 dB at 50 GHz. |
