  • Patent number: 6002372
    Abstract: A retractable antenna for a wireless communication device such as a cellular telephone including a housing having a receptacle at the upper end thereof which is RF coupled to the telephone circuitry. The antenna comprises a metal connector which is RF coupled to the housing receptacle. Telescoping first and second radiators are slidably mounted in the metal connector and may be moved from a fully extended position to a fully retracted position. A helical antenna is operatively supported by the metal connector and is RF insulated therefrom. When the antenna is in its fully retracted position, the helical antenna is in circuit, with the telescoping radiators being out of circuit. When the antenna is in its fully extended position, the telescoping radiators are in circuit and the helical antenna is out of circuit. The overall length of the antenna, when in its fully extended position, is greater than the height of the telephone housing.

  • Patent number: 5999410
    Abstract: A flexible circuit board includes a plurality of discrete circuits for use with different types of rechargeable battery packs. Conductive traces formed on the circuit board include gaps which cause certain portions of the circuitry to be disconnected from the circuit rendering that portion of the circuit inactive. The process of bridging the gaps by attaching one or more components over the gaps causes the corresponding inactive portion of the circuit to be activated. By selectively activating certain portions of the circuit, a desired result is obtained.

  • Patent number: 5686927
    Abstract: A retractable antenna for use with a communications device such as a cellular telephone is described and which may be moved from a fully extended position to a fully retracted position with respect to the telephone housing. The telephone circuitry utilizes a matching circuit to match a high impedance when the antenna is in the extended position. When the antenna is in the retracted position, it changes from a series resonance circuit to a parallel resonance circuit so that it may match the low impedance.

  • Patent number: 5594457
    Abstract: A retractable antenna for use with portable communication equipment comprising two electrically independent electromagnetic radiators in a single package with two modes of operation, retracted and extended. When the antenna is in its retracted position, a short normal-mode monofilar helical radiator is functional. When the antenna is in its extended position, a thin linear radiating element is functional. A switch is provided which connects the internal circuitry of the device to the linear radiating element when the antenna is in its extended position and which connects the internal circuitry of the device to the helical radiator when the antenna is in its retracted position. In each of the extended and retracted positions, the linear radiator and the helical radiator are isolated from one another. A modified form of the antenna is also disclosed.
