Abstract

Dispositif d’antenne sur circuit imprimé et procédé de réalisation d’antenne(s) sur circuit(s) imprimé(s). La présente invention a pour objet un dispositif d’antenne sur circuit imprimé comprenant, d’une part, un circuit imprimé (1) comprenant un circuit d’émission/réception radiofréquence et se présentant sous la forme d’une plaque comprenant deux faces opposées (1a, 1b), à savoir une première face (1a) et une deuxième face (1b), et au moins un côté latéral (1c, 1d, 1e, 1f) reliant lesdites faces opposées (1a, 1b) en formant la bordure du circuit imprimé (1) et, d’autre part, une antenne (2) reliée audit circuit d’émission/réception radiofréquence et réalisée par métallisation sur la surface externe du circuit imprimé (1). L’antenne (2) présente une forme allongée, de section transversale en U, s’étendant le long d’au moins une partie de ladite bordure (1c, 1d, 1e, 1f) du circuit imprimé (1) et comprenant une première aile (2a) longitudinale, une deuxième aile longitudinale (2b) et une troisième aile longitudinale (2c) reliées entre elles et formant chacune une couche de métallisation essentiellement continue sur la surface externe du circuit imprimé (1). La première aile longitudinale (2c) est appliquée sur ladite bordure, tandis que la deuxième aile longitudinale (2a) est appliquée sur la première face (1a) et la troisième aile longitudinale (2b) est appliquée sur la deuxième face (1a). Elle a également pour objet procédé de réalisation d’antenne(s) sur circuit(s) imprimé(s). Figure à publier avec l’abrégé : Fig. 2Antenna device on printed circuit and method for producing antenna(s) on printed circuit(s). The present invention relates to an antenna device on a printed circuit comprising, on the one hand, a printed circuit (1) comprising a radio frequency transmission/reception circuit and being in the form of a plate comprising two opposite faces (1a, 1b), namely a first face (1a) and a second face (1b), and at least one lateral side (1c, 1d, 1e, 1f) connecting said opposite faces (1a, 1b) by forming the border of the printed circuit (1) and, on the other hand, an antenna (2) connected to said radio frequency transmission/reception circuit and produced by metallization on the external surface of the printed circuit (1). The antenna (2) has an elongated shape, of U-shaped cross section, extending along at least part of said edge (1c, 1d, 1e, 1f) of the printed circuit (1) and comprising a first longitudinal wing (2a), a second longitudinal wing (2b) and a third longitudinal wing (2c) connected together and each forming an essentially continuous metallization layer on the external surface of the printed circuit (1). The first longitudinal wing (2c) is applied to said edge, while the second longitudinal wing (2a) is applied to the first face (1a) and the third longitudinal wing (2b) is applied to the second face (1a). It also relates to the process of producing antenna(s) on printed circuit(s). Figure to be published with the abstract: Fig. 2
