Mesure du diagramme de rayonnement de l’antenne

Dans le domaine de la conception d'antennes, les tests et mesures réels d'une antenne avant et après son intégration dans son produit final constituent le moyen le plus précis de valider que les performances de l'antenne sont optimales. Les mesures du diagramme de rayonnement de l'antenne sont essentielles pour comprendre l'intensité angulaire de la direction des ondes radio vers/depuis une antenne testée.

Mesure du diagramme de rayonnement de l’antenne

Visualiser, évaluer, ajuster, valider les diagrammes de rayonnement de l'antenne

Les premières étapes de la caractérisation d’une antenne commencent par la mesure des diagrammes de rayonnement de l'antenne afin de déterminer dans quelles directions et avec quelle intensité l'énergie rayonne de l'antenne. Les résultats présentent l’amplitude et la phase relative de l'antenne testée. Les paramètres S tels que le gain, l'efficacité et la polarisation sont définis alors que la mesure permet de visualiser les diagrammes de rayonnement en 2D ou en 3D.

MVG propose des solutions complètes de test et mesure pour une large gamme de besoins en matière de test d'antenne, de la détermination des diagrammes de rayonnement et des paramètres S aux tests fonctionnels OTA en situation réelle. Les bases de mesure MVG en champ proche, champ lointain ou bases compactes fournissent les éléments de caractérisation permettant de valider les nouvelles conceptions d’antennes en quelques minutes.
