    • 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.
    • 无线电通信装置,第一壳体部分(101)和第二壳体部分(103)。 第二壳体部分可移动地支撑在第一壳体部分上以在延伸位置和折叠位置之间移动。 第二壳体部分在第一壳体部分处于打开位置向外突出。 天线(107)位于第二壳体部分中,天线包括具有第一调谐特性的第一部件(640,749,859,969)和具有第二调谐器的第二部件(647,748,858,968) 特性。 当无线电话被折叠时,天线部件中的一个被调谐为优选特性,并且当天线延伸时天线部件中的另一个被调谐到优选特性。
