Title (EN) A CIRCULARLY POLARIZED ANTENNA FOR RADIO FREQUENCY ENERGY HARVESTING
(FR) ANTENNE À POLARISATION CIRCULAIRE POUR COLLECTE D'ÉNERGIE RADIOFRÉQUENCE
Abstract:
(EN) A circularly polarized (CP) antenna for Radio Frequency energy harvesting comprising: a top substrate; a bottom substrate disposed on a ground plane; a middle substrate disposed between the top substrate and the bottom substrate; a slotted patch comprising more than one slots, the slotted patch being disposed on the top substrate; a slitted patch comprising a plurality of slits, the slitted patch being disposed between the top substrate and the middle substrate; a microstrip feed line disposed between the middle substrate and the bottom substrate; and a via connecting the slotted-circular-patch and the microstrip feed line to enable the slotted-circular-patch to be fed by the microstrip feed line, wherein the more than one slots and the slits are arranged so as to generate more than one orthogonal modes with equal magnitude for receiving RF signals.
(FR) L'invention concerne une antenne à polarisation circulaire (CP) pour une collecte d'énergie radiofréquence comprenant : un substrat supérieur; un substrat inférieur disposés sur un plan de masse; un substrat intermédiaire disposé entre le substrat supérieur et le substrat inférieur; un patch fendu comprenant plus d'une fente, le patch fendu étant disposé sur le substrat supérieur; un patch fendu comprenant une pluralité de fentes, le patch fendu étant disposé entre le substrat supérieur et le substrat intermédiaire; une ligne d'alimentation microruban disposée entre le substrat intermédiaire et le substrat inférieur; et un trou d'interconnexion reliant le patch circulaire fendu et la ligne d'alimentation microruban pour permettre l'alimentation du patch circulaire fendu par la ligne d'alimentation microruban, les plusieurs fentes étant agencées de façon à générer plus d'un mode orthogonal de même amplitude pour recevoir des signaux RF.
