Abstract: The present invention provides a chassis for a radio frequency communication device. The chassis includes an electrically conductive chassis portion having a length and a width, where the electrically conductive chassis portion has a line of symmetry substantially centered widthwise and running along the length of the electrically conductive chassis portion. The chassis further includes an electrically conductive bridge, which has a first end coupled to the electrically conductive chassis portion for enabling a current to pass therebetween. The chassis still further includes a path conductor having a first end and a second end, and a length therebetween. The first end of the path conductor is coupled to the electrically conductive chassis portion at an asymmetrical location relative to the line of symmetry.

Abstract: A method and apparatus for power conservation is provided for a multi-mode wireless communication device (100) capable of operating in a plurality of networks, each of the plurality of networks having a network signal with predetermined spectral characteristics. The wireless communication device (100) includes a variable bandwidth signal detector (140), a threshold detector (145), and a controller (120). The variable bandwidth signal detector (140) receives radio frequency (RF) signals and defines a detection bandwidth for signal detection. The threshold detector (145) is coupled to the variable bandwidth signal detector (140) and detects a network signal within the RF signals in response to determining whether a signal is present within the detection bandwidth having a signal strength greater than a predetermined signal strength.
