Abstract

This work exhibits the design and simulations of an Asymmetric cantilever type RF-MEMS switch with uniform and non-uniform meanders. The Electromechanical and Electromagnetic analysis are performed through the COMSOL multi-physics and HFSS software. Here, the paper aims to maintain the low actuation voltage and enhance the isolation of the switch. The single and non-uniform meanders type of switches shows good results. By comparing two switches, the non-uniform meander type switch shows better performance. The dielectric material is an important factor for getting good capacitance. The switch capacitance in the upper and lower states is 5.42 fF, 8.26 fF, and 3.68 pF, 6.43 pF. The switching time analysis of the switch is obtained as 3 µs 9 µs. The beam materials also impact to reduce the pull-in voltage, and the obtained voltages are 6.3 V and 4.3 V. The switches have good S-parameters, such as return and insertion losses of −36.24 dB, −48. 69 dB and −0.032 dB, −0.051 dB. The isolation has raised both switches as −40.473 dB and −46.182 dB at 1 to 5 GHz frequency range. So, the device becomes a low-frequency range L band, for military and radar applications.
