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 rcctennas having &fferent topology of radiating structures is assessed.
