Title (EN) DECOUPLING BETWEEN PLURAL ANTENNAS FOR WIRELESS COMMUNICATION DEVICE
(FR) CIRCUIT ELECTRONIQUE DE DECOUPLAGE DE PLUSIEURS ANTENNES DESTINE A UN DISPOSITIF DE COMMUNICATION SANS FIL
Abstract: front page image
(EN) An electronic device (10) having multiple antennas (42, 44) and capable of operating in a wireless communication system, where interference between the multiple antennas is minimized using a detuning circuit (46) activated by one or more antennas and resulting in detuning of at least one of the antennas. Activation of the detuning circuit can be accomplished by positioning an antenna to complete the detuning circuit and thereby activate the detuning circuit.
(FR) L'invention concerne un dispositif électronique (10) comprenant plusieurs antennes (42, 44), destiné à être utilisé dans un système de communication sans fil. Ce dispositif électronique (10) utilise un circuit de désaccord (46) activé par une ou plusieurs antennes, conçu pour réduire au minimum les interférences entre les antennes et désaccorder au moins une des antennes. On peut activer le circuit de désaccord en positionnant une antenne de manière à compléter le circuit de désaccord et ainsi activer le circuit de désaccord.
