Abstract

L'invention concerne un circuit frontal radiofréquence et un terminal, comprenant : une antenne principale; et une antenne esclave, l'antenne esclave couvrant une première fréquence de fonctionnement et étant connectée à un multiplexeur, la première fréquence de fonctionnement comprenant des fréquences correspondant à une pluralité de points de fréquence dans une ou plusieurs bandes de fréquence, le multiplexeur étant utilisé pour émettre un signal de l'antenne esclave vers un émetteur-récepteur ou pour émettre un signal de l'émetteur-récepteur vers l'antenne esclave. Grâce à la solution technique de la présente invention, la perte d'insertion d'un premier signal de fréquence de fonctionnement peut être réduite efficacement, et les performances d'émission-réception d'un dispositif de communication sont améliorées.
