A model of receiving-rectifying elements of mm wave band rectennas

Abstract

An approximate model of receiving-rectifying elements (RRE) as periodicity cells of mm wave band (MMWB) rectennas is proposed. It is based on the describing function method, takes into account spurious elements of a Shottky diode case and their series resistance. As compared with existed models it essentially simplifies solving a problem in choosing rational structure of large aperture rectenna systems. On the basis of the developed model, the potential of RREs of MMWB rectennas having different topology of radiating structures is assessed.
