Abstract: Un dispositivo de comunicacion inalámbrica (20) proporciona un estado de adaptacion entre un circuito de radio (28) y un montaje de antena (26) tanto en la posicion contraída como en la posicion extendida y lo hace con un diseño elegante que aumenta la confiabilidad y factibilidad de fabricacion reduciendo el numero y la complejidad de los componentes y moviendo partes mecánicas. Un circuito adaptador (30) que está configurado de acuerdo con un conmutador (32) que responde a la posicion de la antena, proporciona los estados de adaptacion.

Abstract: A retractable antenna assembly provides a substantially matched antenna impedance to a matching circuit (712) of a radiotelephone (200) whether the retractable antenna assembly is in the extended position or the retracted position. In one embodiment parts (304, 312) of a capacitor (714) are integrally formed on an upper portion of the retractable antenna assembly (206) such that when in the retracted position the capacitor (714) contributes to the overall antenna impedance. In another embodiment a capacitor (1302) is integrally formed on the lower portion of the retractable antenna assembly (900).

Abstract: 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.

Abstract: A radio communication device a first housing portion (101) and second housing portion (103). The second housing portion is movably supported on the first housing portion to move between an extended position and a collapsed position. The second housing portion projects outwardly from the first housing portion in the open position. An antenna (107) is positioned in the second housing portion, the antenna includes a first component (640, 749, 859, 969) having a first tuning characteristic and a second component (647, 748, 858, 968) having a second tuning characteristic. One of the antenna components is tuned for a preferred characteristic when the radio telephone is collapsed and the other of the antenna components is tuned to the preferred characteristic when the antenna is extended.
