Abstract: Wireless communications can be improved through a Fresnel lens. The Fresnel lens can be integrated into or onto nonconductive material adapted to serve an alternative useful function (e.g., tent, decorative screen, curtain, umbrella, window tinting film) having at least one surface and that is comprised of the nonconductive material. The Fresnel lens supported by the nonconductive material is configured to improve wireless communications by communication equipment located near the Fresnel lens by increasing signal to noise ratio (SNR) ratio in wireless communication links.

Abstract: 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.

Abstract: A mobile device holder can be provided that includes a screen having a center and a perimeter, a means to retain a mobile device at the center of the screen, a mobile device holder support member defining an outer perimeter of the screen, and conical shape supports configured to create and hold a conical shape of the screen from the perimeter to the center. The mobile device holder support member can be configured to interfaced with a support member associated with a Fresnel lens having a center defined by non-conductive material surrounded by conductive material and position the means to retain a mobile device away from the Fresnel lens when the mobile device support member is interfaced with the support member.

Abstract: A configurable Fresnel lens support structure can include two half-circle support structures deployable at each side of a screen associated with a Fresnel lens and at least one ring clamp attached to each of the half-circle support structures at a center of each of the half-circle support structures. The at least one ring clamp from each of the two half-circle support structures can be adapted to be attached to opposing points on the screen of a Fresnel lens. Magnetic anchors can be disposed on ends of each of the two half-circle support structures to hold the two half-circle support structures onto a metal surface. Alternatively, suctions cups can be disposed on ends of each of the two half-circle support structures to hold the two half-circle support structures onto a smooth surface. The half-circle support structures can be made from spring metal. A ratchet mechanism integrated with the at least one ring clamp to enable the Fresnel lens to be rotated back and forth.
