The paper discusses a rigorous nonlinear/electromagnetic (EM) approach to the simulation of reconfigurable integrated antennas operated by MEMS switches. The patch is characterized as a linear multiport network by EM analy-sis. The MEMS are described as lumped nonlinear components by means of their electromechanical equations. A rigorous analysis of the entire nonlinear (sub)system behavior is then performed by the harmonic balance (HB) tech-nique combined with a numerical implementation of bifurcation theory. This allows an in-depth investigation of the complex stability pattern of the reconfigurable antenna including switching transients and dependence on MEMS switches positions.

Abstract
The paper discusses a rigorous nonlinear/electromagnetic (EM) approach to the simulation of reconfigurable integrated antennas operated by MEMS switches. The patch is characterized as a linear multiport network by EM analy-sis. The MEMS are described as lumped nonlinear components by means of their electromechanical equations. A rigorous analysis of the entire nonlinear (sub)system behavior is then performed by the harmonic balance (HB) tech-nique combined with a numerical implementation of bifurcation theory. This allows an in-depth investigation of the complex stability pattern of the reconfigurable antenna including switching transients and dependence on MEMS switches positions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
