Embodiment Construction

[0023] figure 1 is a plan view of a printed circuit board (PCB) associated with a wireless communication device having a multi-part housing according to an embodiment of the present invention. PCB 100 includes a dielectric board 102 having a planar surface 104 , wherein planar surface 104 includes a first end 106 and an opposing second end 108 . Although the panels are shown as rectangular in shape for simplicity, it should be understood that the invention is not limited to any particular panel shape.

[0024] Figure 2 is figure 1 A partial cross-sectional view of the PCB in Fig. figure 1 The conductive ground plane layer 110 is shown superimposed over the dielectric surface 104 in FIG. 2 . For simplicity, ground plane layer 110 is shown as the topmost (surface) layer. However, it should be understood that in other aspects of the invention not shown, the ground plane layer 110 is an inner layer of a multilayer board formed on the bottom surface 112 of the PCB or formed on ...

Abstract

A wireless communication device is provided with a multipart case, having electrical interfaces that encourage the flow of radiation frequency ground current between case sections. The multipart case has a first planar groundplane section and a second planar groundplane section. For example, the multipart case design may be a slider, double slider, multiple hinge, flip, or swivel case. The second planar groundplane is substantially coplanar with the first groundplane in a case open position, and substantially bi-planar with the first groundplane in a case closed position. The wireless device also includes an antenna located adjacent the second groundplane section first end. A first and a second interface electrically connect the first groundplane section to the second groundplane section second end (the end opposite the antenna).

Description

technical field [0001] The present invention relates generally to wireless communications, and more particularly to a wireless device having an electrical interface between multipart cases that optimizes ground current conduction at antenna radiation frequencies. Background technique [0002] Consumers increasingly demand smaller and feature-rich wireless communication devices, such as cellular (mobile) telephones. Smaller mobile phones with more functions and features can be produced with dual housing parts. One such multi-part configuration is the flip phone. Flip phones open like clamshells. Other configurations include slide phones and rotary phones. In a slide phone, part of the mobile phone housing slides relative to other parts. In a rotary phone, one part of the mobile phone is swiveled open relative to other parts. A slide phone is shown in Application Serial No. 10 / 931,712, filed September 1, 2004, assigned to the assignee of the present application, the discl...
