Title
(EN) HIGH-FREQUENCY SIGNAL TRANSMISSION/RECEPTION DEVICE
(FR) DISPOSITIF D'ÉMISSION/RÉCEPTION DE SIGNAL HAUTE FRÉQUENCE
Abstract
(EN) The present disclosure relates to radio engineering, and more specifically to high-frequency (HF) signal transmission/reception devices based on photoconductive switching elements. An HF signal transmission/reception device comprises a signal electrode with matching elements disposed along an edge thereof; a ground electrode, a dielectric layer between the signal electrode and the ground electrode, photoconductive elements(PE) each electrically connected to the signal electrode and the ground electrode and arranged in a grid, an excitation signal feed point, and load elements electrically connected to the matching elements. The photoconductive elements each have a switched-off state in the absence of a control light flux and a switched-on state in the presence of a control light flux, The switched-on photoconductive elements form a reflection profile of the signal supplied from the excitation signal feed point. The distance between adjacent photoconductive elements is less than half the wavelength of the excitation signal.
(FR) La présente invention concerne le domaine de l'ingénierie radio, et plus particulièrement des dispositifs d'émission/réception de signaux haute fréquence (HF) basés sur des éléments de commutation photoconducteurs. Un dispositif d'émission/réception de signal HF comprend une électrode de signal avec des éléments d'adaptation disposés le long d'un de ses bords ; une électrode de masse, une couche diélectrique entre l'électrode de signal et l'électrode de masse, des éléments photoconducteurs (PE) chacun électriquement connecté à l'électrode de signal et à l'électrode de masse et disposé selon une grille, un point d'alimentation de signal d'excitation, et des éléments de charge connectés électriquement aux éléments d'adaptation. Les éléments photoconducteurs ont chacun un état éteint en l'absence d'un flux lumineux de commande et un état allumé en présence d'un flux lumineux de commande, les éléments photoconducteurs commutés forment un profil de réflexion du signal fourni par le point d'alimentation de signal d'excitation. La distance entre les éléments photoconducteurs adjacents est inférieure à la moitié de la longueur d'onde du signal d'excitation.
