Means for supporting wireless Fresnel lens over a mobile device to enhance antennae reception of RF signals
A Fresnel lens is adapted to be attached to a button associated with an expandable grip structure for a mobile device. The expandable grip structure can include a collapsible membrane formable into a conical shaped when expanded from a flat position to an expanded position, the button formed at one end of the collapsible membrane and having an outer perimeter and a surface, and a base formed at a second end of the collapsible membrane. The collapsible membrane can be expanded and moved by the base along a back surface of a mobile device to a location on the back surface that enables the Fresnel lens to enhance radio frequency reception by the mobile device.
1 . A Fresnel lens-enhanced expandable grip structure for use with mobile devices, comprising:
a collapsible membrane, wherein the collapsible membrane form into a conical shaped when expanded from a flat position to an expanded position;
a button formed at one end of the collapsible membrane, the button having an outer perimeter and a surface;
a base formed at a second end of the collapsible membrane; and
a Fresnel lens disposed on the outer perimeter and surface of the button;
wherein the base can be moved along and attached to a backside of a mobile device and the collapsible membrane expanded to enable the Fresnel lens to enhance radio frequency reception by the mobile device.
2 . The Fresnel lens-enhanced expandable grip structure of claim 1 , further comprising a suction cup attached to an outer surface of the base, said suction cup adapted for attachment to the back surface of the mobile device to thereby affix the Fresnel lens at select locations over the back surface of the mobile device.
3 . The Fresnel lens-enhanced expandable grip structure of claim 1 , wherein said base further comprises a slidable clip, said slidable clip adapted to attach to and slide along slots formed in sides of a mobile device protective cover to thereby move the Fresnel lens over the back surface of the mobile device.
4 . The Fresnel lens-enhanced expandable grip structure of claim 1 , wherein the Fresnel lens further comprising an adhesive backside, said adhesive backside adapted to attached the Fresnel lens to a surface of the button.
5 . The Fresnel lens-enhanced expandable grip structure of claim 1 , wherein the Fresnel lens further comprises a carrier, said carrier adapted to attach to at least one of the button or expandable membrane.
6 . The Fresnel lens-enhanced expandable grip structure of claim 1 , wherein a combination of expanding the collapsible membrane and movement of the expandable grip structure and the Fresnel lens along the surface of the provides improved signal reception from transceivers with respect to an internal antenna associated with the mobile device.
7 . A Fresnel lens for use with mobile devices, comprising a Fresnel lens adapted with at least one of an adhesive or a carrier, wherein the Fresnel lens is adapted to be attached to at least one of an outer perimeter and surface of a button associated with a collapsible membrane adapted to be moved along and attached to a backside of a mobile device and the collapsible membrane further adapted to be expanded to enable the Fresnel lens to enhance radio frequency reception by the mobile device.
8 . The Fresnel lens of claim 7 , further comprising a base attached to the collapsible membrane opposite the button, said base including a suction cup attached to an outer surface of the base, said suction cup adapted for attachment to the back surface of the mobile device to thereby affix the Fresnel lens at select locations over the back surface of the mobile device.
9 . The Fresnel lens of claim 7 , further comprising a base attached to the collapsible membrane opposite the button, said base further comprises a slidable clip, said slidable clip adapted to attach to and slide along slots formed in sides of a mobile device protective cover to thereby move the Fresnel lens over the back surface of the mobile device.
10 . The Fresnel lens of claim 7 , wherein the Fresnel lens further comprises an adhesive backside, said adhesive backside adapted to attach the Fresnel lens to a surface of the button.
11 . The Fresnel lens of claim 7 , wherein said carrier is adapted to attach to at least one of the button or expandable membrane.
12 . The Fresnel lens of claim 7 , wherein a combination of expanding the collapsible membrane and movement of the expandable grip structure and the Fresnel lens along the surface of the provides improved signal reception from transceivers with respect to an internal antenna associated with the mobile device.
13 . A method for improving radio frequency reception by mobile devices, comprising:
providing a Fresnel lens adapted to be attached to a button associated with an expandable grip structure, wherein the expandable grip structure includes a collapsible membrane formable into a conical shaped when expanded from a flat position to an expanded position, the button formed at one end of the collapsible membrane and having an outer perimeter and a surface, and a base formed at a second end of the collapsible membrane;
expanding the collapsible membrane and moving the base along a back surface of a mobile device to a location on the back surface that enables the Fresnel lens to enhance radio frequency reception by the mobile device.
14 . The method of claim 13 , further comprising the step of attaching the base to the back surface of the mobile device with a suction cup provided on an outer surface of the base once enhanced radio frequency reception is achieved by the Fresnel lens.
15 . The method of claim 13 , wherein the base is provided in the form of a clip configured to slidably attach to grooves formed in a protective case and to slide along the back surface of the mobile device, wherein the base is moved along the back surface by sliding the clip, and thereby the collapsible membrane, button and Fresnel lens, along the back surface of the mobile device.
