Abstract

La présente demande divulgue un dispositif électronique. Le dispositif électronique décrit dans des modes de réalisation de la présente demande comprend quatre antennes à bande basse (LB), et les quatre antennes LB forment un système de quatre antennes LB à très faible ECC, de telle sorte que l'ECC entre les antennes LB est considérablement réduit, l'ECC d'une antenne MIMO est réduit, et le taux de débit d'un système MIMO est augmenté, ce qui permet d'améliorer la capacité de canal et d'augmenter la vitesse de transmission de données. De plus, les quatre antennes LB sont réparties sur quatre bords latéraux du dispositif électronique, et, pour divers états portatifs du dispositif électronique, au moins deux antennes LB fournissent toujours des signaux quelle que soit la manière dont les au moins deux antennes LB sont tenues, de telle sorte que le dispositif électronique maintient de bonnes performances de communication, améliorant ainsi l'expérience de l'utilisateur.
