    • An antenna system for a communication device. A whip antenna is surrounded by a helical antenna. A switch couples the helical antenna to the signal source when the whip antenna is in a retracted position. The whip antenna is comprised of an upper conductive portion, a lower conductive portion, and a dielectric portion which isolates the upper and lower conductive portions from each other. A conductive sleeve member surrounds the whip antenna and is slidably mounted thereon. In a first embodiment, when the whip antenna is extended, the conductive sleeve member slides over the dielectric portion, coupling the upper and lower conductive portions together. As the whip antenna is retracted, the helical antenna pushes the conductive sleeve member to the top end of the whip antenna, isolating the whip antenna from the helical antenna. In a second embodiment, the helical antenna is an integral part of the conductive sleeve member.
    • 一种用于通信设备的天线系统。 鞭状天线被螺旋天线包围。 当鞭状天线处于缩回位置时,开关将螺旋天线耦合到信号源。 鞭状天线包括上部导电部分,下部导电部分和将上部和下部导电部分彼此隔离的电介质部分。 导电套筒构件围绕鞭状天线并可滑动地安装在其上。 在第一实施例中,当鞭状天线延伸时,导电套筒构件在电介质部分上滑动,将上部和下部导电部分连接在一起。 当鞭状天线缩回时,螺旋天线将导电套筒构件推到鞭状天线的顶端,将鞭状天线与螺旋形天线隔离。 在第二实施例中,螺旋天线是导电套筒构件的整体部分。

    • A selectively coupled two-piece antenna for use in a mobile phone having a casing and radio frequency (RF) communications circuitry includes a composite radiator that is selectively extendable from and retractable into the casing and a communications interface that is connected to the RF communications circuitry. The composite radiator has first and second radiating elements, and a connecting element. When the composite radiator is extended, the connecting element connects the first and second radiating elements. In this position, the communications interface connects the RF communications circuitry to the first and second radiating elements. Thus, the RF communications circuitry transmits and/or receives RF signals through both the first and second radiating elements as a top loaded antenna. However, when the composite radiator is retracted, the connecting element electrically isolates the first and second radiating elements.
    • 一种用于具有壳体和射频(RF)通信电路的移动电话中的选择性耦合的两件式天线包括可选择性地从壳体中伸出并可缩回到壳体中的复合辐射器,以及连接到RF通信电路的通信接口 。 复合散热器具有第一和第二辐射元件和连接元件。 当复合散热器延伸时,连接元件连接第一和第二辐射元件。 在该位置,通信接口将RF通信电路连接到第一和第二辐射元件。 因此,RF通信电路通过第一和第二辐射元件作为顶部加载天线发射和/或接收RF信号。 然而,当复合散热器缩回时,连接元件电隔离第一和第二辐射元件。
