ABSTRACT Rectennas are key contributors in wireless power transmission. Such prominent technology requires intensive works to gain a better performance thus a reliable energy source. In this paper, we present an electromagnetic model of rectenna using nonlinear resolution approach. This was achieved by a hybrid MoM-GEC (the Moments method combined to the generalized equivalent circuit) and the Harmonic balance method. The structure presenting the rectenna was given in a network form making it a flexible and reconfigurable model. The proposed method was demonstrated using a patch antenna and a Schottky diode as a rectifier circuit. The given current density and field distributions validated using HFSS software proves the accuracy of the obtained solutions. Moreover, a study of the RF-DC conversion efficiency is presented to discuss the performance of the rectenna. Finally, results show that this is a simple but effective technique to study the rectifying antenna for different topologies and technologies.
