  • Patent number: 7725083
    Abstract: A wireless communication device such as a cellular telephone handset is disclosed including a housing having a transceiver circuit disposed therein. An internal antenna is also disposed within the housing which is RF connected to the transceiver circuit. An external, retractable antenna is mounted on the housing and is selectively movable between a retracted position and an extended position. The external, retractable antenna is RF connected to the transceiver circuit. When the external antenna is retracted, the internal antenna functions as a primary antenna. Should the need arise, the external antenna may be extended to improve the quality of the radio signals.

  • Patent number: 7183982
    Abstract: Operating parameters of a planar antenna are controlled by providing a planar metal radiating element having an edge, by providing a slot within the radiating element, the slot having side walls, an open slot-end that lies on the edge of the radiating element, and a closed slot-end the lies within the radiating element, and by providing a thin, line-like, and metal segment, at least a portion of which is coplanar with the radiating element and that extends from the open slot-end to the closed slot-end without physically engaging the slot's side walls. The metal segment can be connected to the antenna's ground plane to thereby form a parasitic element, or the metal segment can be connected to the radiating element to thereby form an extension of the radiating element.

  • Patent number: 7129894
    Abstract: A single antenna element with a switchable extension may be used to change the size of the radiating surface and provide an antenna that has two or more separate center frequencies. The range of frequencies that may be tuned by the antenna is enhanced, while maintaining relatively low complexity tuning and matching circuitry. Switching for the extension is performed by a switching element that is located at the point of connection of the extension to the antenna element. A control line supplies a control signal to the switching element to enable and disable the extension. The control line is positioned in close proximity to the antenna element to enhance coupling between the antenna element and the control line.
