Abstract
We propose a nonlinear model of a resistive MEMS switch. We describe the nonlinear behaviour of the switch by exploiting an extended harmonic balance (HB) technique allowing the efficient calculation of distortion effects due to MEMS nonlinearities. A comparison with the corresponding capacitive model is also given. As an illustrative example, the results of the simulation of a reconfigurable integrated antenna operated by commercial MEMS switches are compared to measurements.
