An accurate linear electrical model applied to a series and parallel 2.45 GHz dual-diode rectenna array
Résumé
This paper reports a simple linear equivalent circuit model of a 2.45-GHz dual-diode rectenna. This model is constituted by an internal voltage source Vrect and a linear resistance Rrect. The proposed model was used to estimate the dc output of a two-elements array interconnected as well as in series or in parallel configurations. Measurements show good agreements with those obtained from this model in the case of balanced or unbalanced situations. The proposed model can easily be used to accurately estimate the dc-output performances of a large number elements arrays, interconnected either in series or in parallel.
