Abstract
Une structure d'antenne de carte à circuit imprimé pour la transmission de l'énergie de fréquences radio. L'antenne de carte à circuit imprimé de la présente invention comprend un sous-assemblage de cartes à circuit ayant une section de composante de montage et une section d'antenne. La section d'antenne de la carte à circuit comprend une paire de traces d'antenne qui fonctionnent comme les deux faces d'une antenne dipôle. Chaque trace d'antenne comprend une bande rayonnante où la combinaison de la paire de bandes rayonnantes a une longueur inférieure à la moitié de la longueur d'onde du rayonnement souhaité transmis. Chaque trace d'antenne comprend une bande d'adaptation d'impédance ayant une structure serpentiforme et accouplée à la bande rayonnante. La bande d'adaptation d'impédance correspond à l'impédance souhaitée pour le circuit de pilotage de l'antenne.
