Description

ABSTRACT:
An electronic device includes an antenna enclosure provided with a circuit on which an antenna is etched and a balun circuit for feeding the antenna, itself connected to a microelectronic enclosure fitted with an airtight connection having a sealed glass bead with at least one conducting wire passing through it. The balun circuit has at least two different tracks on each side of a dielectric substrate. At least one immediate electrical contact is provided between the conducting wire of the enclosure and one of the tracks of the balun circuit, at the same time as a direct mechanical fixing of the antenna enclosure to the microelectronic enclosure, accompanied by another connection of the same type or an earth transfer conductor which is connected to the other balun track and is in contact with the microelectronic enclosure.
