Abstract

La présente invention concerne un assistant numérique personnel (PDA) (10) à utiliser dans un environnement industriel qui comprend un module d'extension (100) placé pour être fixé de manière amovible à une face arrière du PDA (10) et donc lui être couplé de manière opérationnelle. Le module d'extension (100) comprend une antenne HF (120) à utiliser pour établir une communication sans fil entre le PDA (10) et un dispositif distant. L'antenne est fixée sur un matériel formant un boîtier résistant aux chocs du module d'extension (100), aidant ainsi à s'assurer que l'antenne reste en position au cas où le PDA (10) tombe. L'antenne (120) est positionnée sur le PDA (10) de sorte qu'elle ne soit généralement pas couverte par la main de l'utilisateur qui saisit le PDA (10) pour s'en servir. La plage de fonctionnement efficace de l'antenne est donc généralement maximisée. L'antenne peut être fournie dans un capuchon qui se fixe sur un connecteur d'extension (130) du module d'extension (100).
