摘要： A quadrifilar helical antenna comprising two pairs of filars having unequal lengths and phase quadrature signals propagating thereon. A conductive H-shaped impedance matching element matches a source impedance to an antenna impedance. The impedance matching element having a feed terminal at the center thereof from which current is supplied to the two filars of each filar pair disposed about an edge of the impedance matching element and symmetric with respect to a center of the impedance matching element. The impedance matching element further comprises a reactive element for matching the antenna and source impedances.

摘要： An antenna structure for use in a communications device for reducing a user's SAR exposure. In addition to the conventional antenna elements, e.g., a radiating element and a ground plane, the antenna structure of the present invention comprises a conductive element for directing radio frequency energy emitted by the radiating element away from the user, thereby reducing the user's SAR exposure. The conductive element can be disposed on an interior or an exterior surface of a case enclosing the communications device.

摘要： Disclosed herein is a method of providing alarm service upon movement out of a safety zone in a mobile communication network. The method is implemented in such a way as to acquire past location registration information for a ward's mobile terminal designated by a subscriber (guardian), the past location registration information being base station identifiers associated with base stations at which the past locations of the ward's mobile terminal has previously been registered, store the acquired past location registration information to a My Base Station DB allocated to the ward, check base station information, associated with a base station at which the current location of the ward's mobile terminal has been registered, at the time of an observation request, determine whether base station information has been stored in the My Base Station DB, detect movement out of the safety zone when the base station information has not been stored in the My Base Station DB, and notify the subscriber of movement out of the safety zone.
