  • Wireless communication device with variable antenna radiation pattern and corresponding method
    Patent number: 7024232
    Abstract: A communication device 10 and a corresponding method are arranged for changing the radiation pattern of an antenna 14, where the radiation pattern of the antenna 14 is set to a half-space pattern if the communication device 10 is in close proximity to an object. A reflector 18 is activated to produce the half space radiation pattern. The reflector 18 is deactivated to produce the full space pattern. A switching device 26 determines the state of the reflector 18. A sensing and control device 23 controls the state of the switching device 26.
    Type: Grant

  • Hand held communication device with decoupled antenna
    Publication number: 20040204199
    Abstract: A hand held communication device (10) employs a first flip portion (14) that is pivotal with respect to a base portion (12), wherein the first flip portion (14) includes an antenna (20) and at least a power amplifier circuit (200) operatively coupled to an antenna (20). A second flip portion (16), also pivotal with respect to the base portion (12), includes at least one of a display (24) and a microphone (22). The first flip portion (14) preferably fits within a recessed area (46) of the second flip portion (16) and deploys automatically when the hand held device is opened.
