Multiple-Body-Configuration Multimedia and Smartphone Multifunction Wireless Devices

摘要

A multifunction wireless device having at least one of multimedia functionality and smartphone functionality, the multifunction wireless device including an upper body and a lower body, the upper body and the lower body being adapted to move relative to each other in at least one of a clamshell, a slide, and a twist manner. The multifunction wireless device further includes an antenna system disposed within at least one of the upper body and the lower body and having a shape with a level of complexity of an antenna contour defined by complexity factors F21 having a value of at least 1.05 and not greater than 1.80 and F 32 having a value of at least 1.10 and not greater than 1.90.

主权项

1. A handheld multifunction wireless device comprising:
a touch screen; a digital camera; a component to reproduce digital music; a microphone; and an antenna system comprising a ground plane layer and at least two antennas within the handheld multifunction wireless device, the antenna system comprising:
a first antenna having a conductive plate configured to simultaneously support radiation modes for at least first, second and third frequency bands, the first antenna being proximate to a first short side of a ground plane rectangle defined by the ground plane layer, the first antenna defining an antenna box, an orthogonal projection of the antenna box along a normal to a face with a largest area of the antenna box defining an antenna rectangle, a perimeter of the first antenna defining a first antenna contour whose length is greater than four times a diagonal of the antenna rectangle; anda second antenna configured to provide wireless connectivity in at least two frequency bands, wherein a perimeter of the second antenna element defines an antenna contour having a level of complexity defined by complexity factor F21 having a value of at least 1.20 and F32 complexity factor having a value of at least 1.35.
