the relationship between the structure parameters of the RF MEMS series switch and its microwave characteristics and the mechanical behaviors is studied respectively.Based on the findings
the better geometric parameters of the cantilever is found.An RF MEMS switch is designed.Experiment shows that at 10V
the deflections of the cantilever are around 3μm.At 5GHz
an echo loss is smaller than 0.2dB and isolation is larger than 35dB.
