Abstract: A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack. The multilayer optical stack of core layer 202 includes two alternating polymeric layers. The multilayer polymer optical film may optionally also include a protective layer 204 (for example, a hardcoat or an over laminate) that is positioned between the viewer and the core layer. The protective layer 204 may include one or more UV absorbers to aid in durability of the multilayer polymer optical film against UV-degradation. Multilayer polymer optical film 200 may optionally also include an adhesive layer 208 that is positioned between the core layer 202 and a surface onto which the multilayer polymer optical film is to be adhered.

Abstract: A repeater device comprises a periodic array of alternating metallic phase shifting elements, the array being periodic in at least one axis, formed on a first surface of a dielectric substrate, with an opposite surface of the dielectric substrate having a ground plane formed thereon, wherein each phase shifting element provides from 0° to 360° phase shifting in the microwave frequency range. The repeater device can be utilized in a microwave network.

Abstract: A broadband antenna includes a uniplanar structure having a plurality of separate and contiguous metallic elements. A first element comprises a substantially circular metallic element having a flattened portion. A second element comprises a substantially linear metallic strip connected to an edge of the first element. The antenna further includes a pair of substantially rectangular side elements disposed on opposite sides of the second element that are electrically isolated from the first and second elements. The antenna can achieve a return loss better than 10 dB over a broadband range.

Abstract: An antenna for wireless communication comprises a dielectric substrate having a first side and an opposite second side. A first major arm having a first modified log-spiral spiral pattern is disposed on the first side of the dielectric substrate. A second major arm having a second modified log-spiral pattern is disposed on the second side of the dielectric substrate, wherein the first and second major arms are formed from a conductive material. A connector coupling is disposed at a center of the modified log-spiral patterns, the connector coupling having a first portion coupled to the first major arm and a second portion coupled to the second major arm. The antenna is self-complementary. The antenna can achieve a return loss better than 10 dB over a broadband range.
