Abstract

La présente invention concerne des structures d'antenne sans fil entrées multiples sorties multiples et une carte de circuit imprimé. Les structures comprennent une pluralité d'antennes, colocalisées au niveau d'un coin de la carte de circuit imprimé et configurées pour produire des diagrammes de rayonnement ayant différentes directions de faisceau principal afin de réaliser un diagramme synthétique à couverture complète, et la pluralité d'antennes sont couplées à une pluralité de ports d'alimentation de la carte de circuit imprimé, respectivement, et couplées à la masse de la carte de circuit imprimé. Par conséquent, l'invention décrit des solutions d'antenne permettant d'améliorer la couverture sans fil entrées multiples sorties multiples avec une conception simple et des coûts de mise en œuvre plus bas.
