Abstract:In this study, a step-down structured switch is designed and compared with and without optimised dimensions to increase the isolation and to lower the pull-in-voltage with respective electromechanical and electromagnetic characteristics. The optimised switch is designed to operate only in K-band frequencies with the high isolation of −54.17 dB at the centre frequency of 22 GHz. The antenna using MEMS switch exhibits a frequency shift of 1.5 GHz from the first case to the second case and 7.4 GHz in the third ca… Show more
