    • A multiband element antenna (120) used in combination with a unique metal chassis design that enhances antenna performance and that enables the design of a compact and efficient antenna system. A cellular flip phone (100) that has a conductive chassis includes a flip up antenna (120) that pivots between an extended and a retracted position. The antenna (120) pivots at a point that is located on one edge of the top of the cell phone body (102). The conductive chassis of the flip cover (104) is grounded to the flip phone body (102) at a single point or single surface that is substantially opposite the antenna RF feed (122). Conductive surfaces of the cellular flip phone body (102) are grounded at a single point that is near the antenna RF feed point (122). This grounding arrangement has been found to control the flow of induced currents on the conductive portions of the flip cover (104) and body (102), thereby improving the performance of the device's antenna (120).
    • 多带元件天线(120)与独特的金属底盘设计结合使用,可增强天线性能,并实现紧凑而高效的天线系统的设计。 具有导电底盘的蜂窝翻盖电话(100)包括在延伸位置和缩回位置之间枢转的翻转天线(120)。 天线(120)在位于蜂窝电话主体(102)的顶部的一个边缘上的点枢转。 翻盖(104)的导电底盘在与天线RF馈送(122)基本相对的单个或单个表面处接地到翻转电话主体(102)。 蜂窝翻盖电话主体(102)的导电表面在靠近天线RF馈电点(122)的单个点处接地。 已经发现这种接地装置可以控制翻盖(104)和主体(102)的导电部分上的感应电流的流动,从而提高装置的天线(120)的性能。

    • A dual radiator galvanically coupled antenna for a portable communication device. The antenna includes separate elongate and upper radiators that respectively galvanically couple to phone circuits in extended and retracted states. An insulator, preferably thermoplastic, mechanically connects and electrically separates the elongate and upper radiators. In a preferred embodiment, a shaped conductor provides an electrode with a cup having a thinned wall which crimps onto an end of an upper helical radiator to make electrical contact thereto. The shaped conductor also forms an exposed galvanic electrical contact, and an enlarged knurled portion for mechanical connection to the insulator. A separate enlarged galvanic contact is formed at a terminal end of the elongate conductor. An additional preferred embodiment includes an upper rod galvanically coupled to the electrode and electrically parallel with the helical radiator.
