Abstract

La présente invention concerne un dispositif et un procédé d'émission et de réception de signaux de fréquences radioélectriques. Le dispositif comprend : un ou plusieurs processeurs de fréquences radioélectriques, configurés pour traiter un signal de fréquence radioélectrique à envoyer et pour émettre le signal de fréquence radioélectrique traité ; un contrôleur, couplé au processeur ou aux processeurs de fréquence radioélectrique et configuré pour recevoir le signal de fréquence radioélectrique traité en provenance du ou des processeurs de fréquence radioélectrique et pour émettre, avec un déclenchement périodique et selon une classification du signal de fréquence radioélectrique traité, le signal de fréquence radioélectrique traité à une antenne correspondant à la classification du signal de fréquence radioélectrique traité ; et de multiples antennes, couplées au contrôleur et configurées pour recevoir, en provenance d'un sélecteur, le signal de fréquence radioélectrique traité et accomplir la résonance sur le signal de fréquence radioélectrique traité. La solution technique fournie par la présente invention réduit la difficulté d'implémentation de l'antenne et améliore le rendement de l'antenne et les performances radioélectriques d'un terminal à plusieurs modes et à plusieurs bandes.
