Abstract: In accordance with the disclosed embodiment of the present invention, there is provided a technique to control and manage where the currents flow produced by noise producing components such as transmitters, and how to specifically exclude them from critical areas, such as where noise sensitive components are disposed. Such noise sensitive components may include oscillators and other components. According to a disclosed example of the present invention, an electrically-isolated area at least partially surrounds one or more noise-sensitive components. As disclosed herein, a gap in the elongated area receives one or more traces such as power plane, ground plane and signal traces for the partially surrounded component or components.

Abstract: A system and method for providing a global positioning system (GPS) enabled antenna system are provided. The GPS enabled antenna may be used, for example, on a wireless communications device such as a wireless handset. The wireless communications device includes a GPS switching module coupled to a conventional communications antenna, including its associated circuitry. The GPS switching module is adapted to selectively couple the communications antenna to GPS matching circuitry. In this arrangement, the GPS matching circuitry adjusts impedance at approximately 1575 MHz to more closely match the communications antenna to GPS circuitry in the wireless device.

Abstract: A method and apparatus is disclosed for improving signal reception in a wireless communication device by selectively processing one of two or more signals received over two or more antennas that are configured at least partially orthogonal. In one embodiment, the signal source selection is based on comparison of a signal error rate to a threshold value. Error rates in excess of the threshold value may initiate a switching apparatus to selectively enable signal reception from a different antenna to improve the error rate. In one embodiment, amplifiers are located between the switching apparatus and the two or more antennas to thereby reduce noise. In an alternative embodiment control signals selectively enable and disable the amplifiers to control signal reception.
