Embodiment Construction

[0013] refer to figure 1 , showing an embodiment of the invention in exploded view. The RF shielding device of the present invention is comprised of a frame member 102 configured and dimensioned to enclose at least a top surface of a mobile device 110 . Frame members 102 are specifically sized for the corresponding mobile device model, so one frame member 102 can be specific to 4 / 4s or 5 / 5s or 6, while a second frame member 102 with a different size could be specific to the Google Nexus 10.

[0014] Frame member 102 may be formed from plastic, silicone, thermoplastic polyurethane, rubber, or metal frame 102a. The frame member 102 has a display void 102b centrally formed thereon. The display void 102b is aligned with an area of ​​the corresponding mobile device 110 that corresponds to the display 110a. Thus, the frame 102a surrounds the perimeter of the mobile device 110 such that the entirety of the display 110a is aligned with and visible through the display void 102b. ...

Abstract

An RF shielding device of a mobile device includes a conductive grid having a horizontal line trace and a vertical line trace in electrical contact with each other, a conductive trace, a first insulating film and a second insulating film, wherein the conductive trace is disposed around a periphery of the conductive grid, the conductive trace is in electrical contact with both ends of each of the horizontal line trace and the vertical line trace; the first insulating film is disposed on a top surface of the conductive grid; and the second insulating film is disposed on the conductive trace anda bottom surface of the conductive grid. The first insulating film and the second insulating film have a transparent material. The first insulating film and the second insulating film are transparentso that a display of the mobile device on which the RF shielding device is disposed is allowed to be watched. The vertical line trace and the horizontal line trace are spaced apart to form a grid thatis opaque to signals within a frequency range for mobile communication.

Description

[0001] This application is a branch of a Chinese invention patent application with an international filing date of September 3, 2014 and entered the Chinese national phase on May 2, 2017 with the application number 201480083143.1 and the title of the invention "RF shielding for mobile devices". case application. technical field [0002] The present invention generally relates to radio frequency shielding for mobile cellular or wireless devices including, but not limited to, mobile phones, tablet computers (such as Apple ) and e-book readers (such as Bames&Noble and Amazon ). Background technique [0003] During normal operation, mobile devices emit radio frequency (RF) radiation intermittently during standby periods, and continuously during active calls. In the following, a mobile device includes any device that is portable and equipped with cellular or wireless (eg Wi-Fi, Bluetooth, near field) communication capabilities and a display screen. Examples of mobile devic...
