  • Patent number: 6995716
    Abstract: Selectively engaged antenna matching for a mobile terminal. Antenna matching can be engaged, disengaged, or switched as needed depending on whether a movable cover or clam-shell portion of a mobile terminal is open or closed. A switch can connect a single matching network to a radiating element in one case, and disconnect the single matching network from the radiating element in the other case. Alternatively, the switch can connect one matching network to the radiating element to achieve one matched condition, and the other matching network to the radiating element to achieve the other matched condition. In other embodiments, a switchable matching arrangement can alter the signal and/or ground feed points of an antenna. The technique can be applied to planar, fixed external, or collapsible antennas.

  • Patent number: 6980154
    Abstract: A planar inverted F antenna may be configured for operation at an operating frequency band, and the planar inverted F antenna may include first, second, and third antenna segments, a reference voltage coupling, and a feed coupling. The first and second antenna segments may be separated by at least approximately 3 mm, and the third antenna segment may couple the first and second antenna segments. The reference voltage and feed couplings may both be provided on the first antenna segment, and a current null may be present between the feed and reference voltage couplings at the operating frequency band. Related communications devices are also discussed.

  • Patent number: 6903686
    Abstract: A conductive element with a primary branch and a secondary branch are separated by a bend segment and the signal and ground feeds are positioned adjacent each other on a common portion of the conductive element. The frequencies in the high band may be at least about twice that of the frequencies in the low band. The branches and bend segment are constructed such that the primary branch radiates at both high and low band operation. The two branches combine to form a more efficient high band radiator.

  • Patent number: 6437682
    Abstract: Pressure sensitive direction devices are provided which may facilitate assembly and provide higher tolerance for variation in alignment of components while still providing for pressure sensitive direction detection. The devices of the present invention may be particularly advantageous when integrated into devices, such as cellular radiotelephones, to provide a user interface to facilitate user navigation through increasingly complex menu structures. In various embodiments, the present invention may detect pressure in addition to two and, preferably, at least four directions. In particular embodiments, the devices of the present invention provides a switching device having a plurality of trace grid areas located, for example, on a printed circuit board and actuated responsive to pressure applied by a user through a poly-dome layer where increase pressure results in contact with a greater number of the traces in respective grids.
