Title (EN) RADIO-FREQUENCY ANTENNA SYSTEM BASED ON MODE HYBRIDISATION FOR A NUCLEAR MAGNETIC RESONANCE DEVICE
(FR) SYSTEME D'ANTENNE RADIOFREQUENCE FONDE SUR L'HYBRIDATION DE MODE POUR DISPOSITIF DE RESONANCE MAGNETIQUE NUCLEAIRE
Abstract:
(EN) The invention relates to a radio-frequency antenna system including at least one radio-frequency transmitter and/or receiver (4) and resonators (6) which are mutually electromagnetically hybridised, coupled with the radio-frequency transmitter and/or receiver, and electrically insulated from one another and from the radio-frequency transmitter and/or receiver (4).
(FR) Système d'antenne radiofréquence comprenant au moins un émetteur et/ou récepteur radiofréquence (4) et des résonateurs (6) hybridés électromagnétiquement entre eux, couplés à l'émetteur et/ou récepteur radiofréquence, isolés électriquement les uns des autres et de l' émetteur et/ou récepteur radiofréquence (4).
