Title
(EN) HIGH-FREQUENCY TRANSMISSION LINE USING PRINTED CIRCUIT BOARD FOR MULTIBAND ANTENNA PERFORMANCE IMPROVEMENT
(FR) LIGNE DE TRANSMISSION HAUTE FRÉQUENCE UTILISANT UNE CARTE DE CIRCUIT IMPRIMÉ POUR AMÉLIORATION D'EFFICACITÉ D'ANTENNES MULTIBANDES

Abstract
(EN) The present invention relates to a high-frequency transmission line using a printed circuit board for multiband antenna performance improvement. According to the present invention, a first ground layer (110) extending in one direction and electrically connected to multiple antennas, a first dielectric layer (120) stacked on the first ground layer (110) and extending in the same direction as the first ground layer (110), and a signal transmission line (130) stacked on the first dielectric layer (120) and extending in the same direction as the first dielectric layer (120) are stacked to transmit an electric signal to the multiple antennas. The first ground layer (110) is divided into multiple ground portions which are respectively and independently connected to the multiple antennas. A decline in radio frequency characteristics caused by the separation of the first ground layer (110) is addressed by the shape of the compensation portion of the first ground layer (110) or the supplementary portion of the signal transmission line (130) provided at a position between the multiple ground portions.
(FR) La présente invention porte sur une ligne de transmission haute fréquence qui utilise une carte de circuit imprimé afin d'améliorer l'efficacité d'antennes multibandes. Selon la présente invention, une première couche de masse (110), s'étendant dans une direction et électriquement connectée à de multiples antennes, une première couche diélectrique (120), empilée sur la première couche de masse (110) et s'étendant dans la même direction que la première couche de masse (110), et une ligne de transmission de signal (130), empilée sur la première couche diélectrique (120) et s'étendant dans la même direction que la première couche diélectrique (120), sont empilées afin de transmettre un signal électrique aux multiples antennes. La première couche de masse (110) est divisée en de multiples parties de masse qui sont respectivement et indépendamment connectées aux multiples antennes. Une dégradation des caractéristiques radiofréquence due à la séparation de la première couche de masse (110) est traitée par la forme de la partie de compensation de la première couche de masse (110) ou de la partie supplémentaire de la ligne de transmission de signal (130) fournie à un emplacement entre les multiples parties de masse.
