A wireless communication device (20) provides a matching state between a radio circuit (28) and an antenna assembly (26) in both its retracted and extended positions, and does so with an elegant design that increases reliability and manufacturability by reducing the number and complexity of components and moving mechanical parts. A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states. Furthermore, the switch (32) can be integrally formed as part of a feed terminal (36), the feed terminal (36) and a ground terminal (38) can hold the antenna in position, and the ground terminal (38) can hold a guiding tube (52). Alternatively, the switch (32) can include a diode (102) and a sensor. The sensor is a rod (46) of the antenna assembly that makes and breaks an electrical path between the feed terminal and the ground terminal to change the state of the diode.
Dispositif de communication sans fil (20) qui assure l'adaptation d'un circuit de radiocommunication (28) à un ensemble antenne (26) en position rétractée et déployée, et dont la conception élégante accroît la fiabilité et la fabricabilité en réduisant le nombre et la complexité des composants et des parties mécaniques mobiles. Un circuit d'adaptation (30), qui est reconfiguré selon la position d'un commutateur (32) sensible à la position de l'antenne, assure l'adaptation. En outre, le commutateur (32) peut être intégralement formé comme partie d'une borne d'alimentation (36). Cette dernière (36) et une borne de mise à terre (38) peut tenir l'antenne en place, et la borne de mise à terre (38) peut tenir un tube de guidage (52). Selon une autre version possible, le commutateur (32) peut comprendre une diode (102) et un capteur. Le capteur est une tige (46) de l'ensemble antenne qui établit et rompt un trajet électrique entre la borne d'alimentation et la borne de mise à terre pour changer l'état de la diode.
