The paper presents a reliable model for the susceptibility analysis of a Rectenna (Rectifying Antenna) in the context of microwave energy transfer. The approach allows to take into account both distributed electromagnetic portions of the antenna and the rectifier circuit including lumped elements. From the 3D electromagnetic modelling of the structure the input impedance is obtained as a function of frequency. Then a rational approximation of the Laplace variable is chosen to describe the port behaviour. The technique provides a straightforward way for a time domain simulation using Pspice or Saber. The proposed approach can be efficiently used to provide a non-linear time-domain study in the framework of EMC (Electromagnetic Compatibility) for various electronic equipments involving printed circuit-boards, internal structures of electronic components or Micro-Electro-Mechanical Systems (MEMS).
