  • Patent number: 8339807
    Abstract: A portable terminal has a first enclosure of a housing having a first interior to contain a plurality of electronic components and a ground. The terminal has a second enclosure of the housing for coupling to the first enclosure, the second enclosure having a second interior to contain an antenna and for facilitating at least one of receiving or transmitting of electromagnetic (EM) signals between the antenna and an environment external to the second enclosure. The terminal has an EM shield positioned at an interface between the first interior and the second interior, the EM shield including electrically conductive material to absorb EM radiation generated by the plurality of electronic components. Also included is an electrically conductive coupling to couple the EM shield to the ground of the first enclosure.

  • Publication number: 20110263270
    Abstract: Described are a method, system, and mobile communication device for sharing a signal received by an antenna. A signal, such as a signal sent from a global positioning system, is received by the antenna. An amplifier is then used to generate an amplified signal. The amplifier is located an attenuation distance away from a noise source. The amplified signal is divided into a first divided signal and a second divided signal, which are respectively transmitted to first and second signal utilization modules. While being transmitted from the antenna to the first and second signal utilization modules, the signal suffers propagation losses. While locating the amplifier remote from the noise source decreases noise strength, which positively contributes to signal-to-noise ratio, it also increases propagation losses, which negatively contributes to signal-to-noise ratio.
