    • An antenna system for a communication card provides wireless or radio frequency (RF) communication with other networks or communication systems. The antenna system includes an antenna attached to a retractable platform that is selectably movable between an extended position and a retracted position. When wireless communication is desired, the retractable platform is located in the extended position and the antenna is substantially disposed outside of the body of the communications card. When wireless communication is not desired, the retractable platform and antenna are stored inside the body of the communications card in the retracted position. Desirably wireless communication is automatically available when the retractable platform is in the extended position, and wireless communication is automatically unavailable when the retractable platform is in the retracted position.
    • 用于通信卡的天线系统提供与其他网络或通信系统的无线或射频(RF)通信。 天线系统包括附接到可伸缩平台的天线,其可选地在伸出位置和缩回位置之间移动。 当需要无线通信时,可伸缩平台位于延伸位置,并且天线基本上设置在通信卡的主体的外部。 当不期望无线通信时,可伸缩平台和天线被存储在通信卡的主体内处于缩回位置。 当可伸缩平台处于伸展位置时,期望无线通信是可自动获得的,并且当可伸缩平台处于缩回位置时,无线通信自动不可用。
