A radio communication device includes a radio signal source (415) positioned in the first housing portion (101). A second housing portion (103) has a first end movably supported on the first housing portion such that the housing portions are reconfigurable between an extended position and a collapsed position. A dipole antenna (107) has a first arm (440) positioned in the first housing portion and a second arm (441) positioned in the second housing portion. A respective end of each of the arms is connected to the signal source. Plates (450, 451) are positioned on the first and second housing portions and connected to the antenna arms such that they are capacitively coupled when the housing portions are collapsed and are not coupled when the housing portions are extended.

L'invention est un dispositif de radiocommunication comportant une source de signaux radio (415) montée dans un premier logement (101). L'une des extrémités d'un second logement (103) est supportée de façon mobile par le premier logement de telle façon que ces logements sont reconfigurables entre une configuration d'extension et une configuration d'escamotage. La première branche (440) d'une antenne dipôle (107) est placée dans le premier logement et la seconde branche (441) est placée dans le second logement. L'une des extrémités de chacune des branches est connectée à la source de signaux. Des plaques (450, 451) sont montées sur le premier et le second logements et sont connectées aux branches d'antenne de façon à être couplées capacitivement quand les logements sont en configuration d'escamotage et ne sont pas couplées quand les logements sont en configuration d'extension.
