Title
(EN) MULTI-RADIO FRONT-END CIRCUITRY FOR RADIO FREQUENCY IMBALANCED ANTENNA SHARING SYSTEM
(FR) CIRCUIT FRONTAL MULTI-RADIO POUR SYSTÈME DE PARTAGE D'ANTENNE INSENSIBLE À LA FRÉQUENCE RADIO
Abstract
(EN)
Systems, methods, and devices are provided to efficiently share an antenna between multiple communication systems and allow for the communication systems to be simultaneously connected to the antenna with less attenuation and/or no fluctuation in signal strength. Communication circuitry may include an antenna that transmits and receives electromagnetic radiation. The communication circuitry may also include an antenna port that provides primary access to the antenna with a first attenuation via an antenna port input. Additionally, the communication circuitry may include a coupler attached to the antenna port. The coupler may provide secondary access to the antenna with a second attenuation.
(FR)
L'invention concerne des systèmes, des procédés, et des dispositifs, utilisés pour partager efficacement une antenne entre une pluralité de systèmes de communication et permettre aux systèmes de communication d'être connectés simultanément à l'antenne avec moins d'affaiblissement et/ou aucune fluctuation de l'intensité du signal. Un montage de circuits de communication peut comprendre une antenne qui émet et reçoit un rayonnement électromagnétique. Le montage de circuits de communication peut également comprendre un port d'antenne qui fournit un accès primaire à l'antenne avec un premier affaiblissement via une entrée de port d'antenne. De plus, le montage de circuits de communication peut comprendre un coupleur fixé au port d'antenne. Le coupleur peut fournir un accès secondaire à l'antenne avec un second affaiblissement.
