Title (EN) TRIPOLE CURRENT LOOP RADIATING ELEMENT WITH INTEGRATED CIRCULARLY POLARIZED FEED
(FR) ÉLÉMENT RAYONNANT À BOUCLE DE COURANT TRIPOLAIRE AVEC ALIMENTATION À POLARISATION CIRCULAIRE INTÉGRÉE
Abstract:
(EN) In accordance with the concepts, systems, methods and techniques described herein a tripole current loop radiating element is provided having three conductors disposed on a substrate with the three conductors being physically spaced apart from each other and arranged to be responsive to radio frequency (RF) signals at a desired frequency range. Each of the three conductors includes a ground via to couple the respective conductor to a ground plane and a signal via to receive RF signals from a single feed circuit. The feed circuit includes a signal port, and first, second and third antenna ports, with each of the antenna ports coupled to a respective one of the three conductors. The feed circuit can provide the RF signals to each of the three conductors having equal amplitudes and distributed with relative phases of 0/120/240° respectively (i.e., phase shifted by 120° from an adjacent conductor).
(FR) Conformément aux concepts, systèmes, procédés et techniques décrits dans la présente invention, un élément rayonnant à boucle de courant tripolaire comprend trois conducteurs disposés sur un substrat avec les trois conducteurs étant physiquement espacés les uns des autres et agencés de façon à être sensibles aux signaux radiofréquence (RF) à une plage de fréquences souhaitée. Chacun des trois conducteurs comprend un trou d'interconnexion de masse pour coupler le conducteur respectif à un plan de masse et un trou d'interconnexion de signal pour recevoir des signaux RF provenant d'un seul circuit d'alimentation. Le circuit d'alimentation comprend un port de signal, et des premier, second et troisième ports d'antenne, chacun des ports d'antenne étant couplé à un conducteur respectif parmi les trois conducteurs. Le circuit d'alimentation peut fournir les signaux RF à chacun des trois conducteurs ayant des amplitudes égales et distribuées avec des phases relatives de 0/120/240° respectivement (c'est-à-dire, déphasées de 120° par rapport à un conducteur adjacent).
