Design of a novel step structure RF MEMS switch for K-band applications

Abstract

In this paper, we have design a proposed step structure RF MEMS switch for K-band applications. The non-uniform meander structure is implemented for both optimized and non-optimized structure and are analyzed to understand the performance characteristics. The simulations are carried out using COMSOL and HFSS and compared to the analytical calculation for validation. The optimized non-uniform meander switch shows a very low pull-in-voltage of 3.82 V an switch is designed to operated only in K-band frequencies with the high isolation of − 54.17 dB at the centre frequency of 22 GHz.
