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. 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).
