Title (EN) A COMMUNICATIONS UNIT WITH A BUILT-IN ANTENNA
(FR) UNITÉ DE COMMUNICATION AVEC ANTENNE INTÉGRÉE
Abstract:
(EN) In a communications unit, such as a headset or a hearing aid, of the wireless type, a metal layer (3) is adhered or secured to its battery (1) by means of a double adhesive tape or spacers (2), so that the battery and the metal layer are capacitively connected to each other. The metal layer (3) is connected electrically to the transmit and receive circuit of the communications unit, which is mounted on a printed circuit board whose ground parts constitute a ground plane. Hereby, a patch antenna is provided, which, although it has small dimensions, has a good directional characteristic, which additionally provides the advantage that radiation from the antenna is directed away from a user's head. A communications unit constructed in this manner is useful in connection with a Bluetooth communications connection.
(FR) La présente invention concerne une unité de communication, comme un casque ou une aide auditive, de type sans fil, dans laquelle une couche métallique (3) est collée ou fixée à sa batterie (1) au moyen d'un adhésif double face ou d'espaceurs (2), de sorte que la batterie et la couche métallique soient reliées de manière capacitive l'une à l'autre. La couche métallique (3) est électriquement raccordée au circuit de transmission et de réception de l'unité de communication, fixée sur une carte à circuit imprimé dont les parties à la terre constituent un plan à la terre. On obtient ainsi une antenne corrective qui, même si elle est de petite dimension, possède de bonnes caractéristiques directionnelles, ce qui apporte en plus l'avantage que les radiations de l'antenne soient éloignées de la tête de l'utilisateur. Une unité de communication ainsi conçue est utile en rapport avec une connexion Bluetooth.
