Abstract

La présente demande divulgue un appareil et un procédé de commutation d'antenne et un dispositif électronique et appartient au domaine technique des communications. L'appareil de commutation d'antenne comprend : un commutateur à bascule ; un module de détection de signal, le module de détection de signal comprenant une deuxième antenne et une unité de détection de signal, et deux extrémités de l'unité de détection de signal étant électriquement connectées à la deuxième antenne et à une première extrémité du commutateur à bascule, respectivement ; M modules de communication, les M modules de communication étant connectés en correspondance biunivoque à M deuxièmes extrémités du commutateur à bascule ; N premières antennes, les N premières antennes étant connectées en correspondance biunivoque avec N troisièmes extrémités du commutateur à bascule. Les N premières antennes sont utilisées pour recevoir différents signaux de communication, respectivement, les différents signaux de communication ayant au moins un paramètre qui diffère. Le module de détection de signal délivre un signal de commutation au commutateur à bascule lorsqu'un signal de communication cible est détecté, de telle sorte que le commutateur à bascule ouvre et ferme un module de communication cible et une première antenne cible. Des premières antennes autres que la première antenne cible parmi les N premières antennes ne sont pas en communication avec l'un quelconque des M modules de communication.
