The instant disclosure relates to EMI shielding structures. A conductive composition is formed that includes a polymer and graphene present as a 3D-matrix therein. Rectangular EMI shielding panels are formed using the composition. Rectangular EMI shielding panels are affixed orthogonal to each other. The EMI shielding panels are successively overlapped to form a plurality of interconnected EMI shielding planes. The EMI shielding panels are affixed to each other to form a helical EMI shielding structure that folds and unfolds along its center axis. The EMI shielding planes are angularly offset from each other about the center axis to form a helical structure when in the unfolded state. The EMI shielding panels include an encapsulating layer and/or metallic layer. The EMI shielding planes rotate about the center axis when the HES structure transitions between the folded and unfolded states.

Electromagnetic interference shielding structures

Embodiments of the present invention relate to communications tarpaulins. In one embodiment, the communications tarpaulins include a textile layer, a plurality of antenna elements, and a communications hub. The communications hub includes a plurality of radio frequency ('RF') connectors. The communications hub is affixed to the textile layer. The RF connectors are each conductively coupled to one of the antenna elements. The RF connectors each demountably receive a communications device. The antenna elements are each affixed to the textile layer and includes a conductive composition. The antenna elements each include a conductive composition. The conductive composition includes a polymer and fully exfoliated single sheets of graphene that are present as a three-dimensional percolated network within the polymer. The textile layer includes a first textile layer and a second textile layer that are coterminous and physically coupled together and thereby form a multilayered structure.

Communications tarpaulin

The present invention relates generally to transmission lines and specifically to textile transmission line assemblies. The textile transmission line assemblies are capable of lateral bending, axial rotation, and stretching without suffering from a statistically significant loss of its performance characteristics. Antenna elements are incorporated with the textile transmission line assemblies (hereinafter 'combination assemblies'). The textile transmission line assemblies can be incorporated in to garments, apparel items, bags, tents, or other textile-based objects. The textile transmission line assemblies are configured to be flexibly affixed to textile items. The textile transmission line assemblies are impact resistant. Wearable communications systems that incorporate at least one textile transmission line assembly and/or combination assembly are also disclosed.

Embodiments of the present invention relate to electromagnetic interference (EMI) shielding structures. Rectangular EMI shielding panels are formed that include a first and second ends. A pair of rectangular EMI shielding panels are affixed orthogonal to each other at their first ends. The pair of rectangular EMI shielding panels are successively overlapped with each other to thereby form a plurality of interconnected EMI shielding planes. The pair of rectangular EMI shielding panels are affixed to each other at their second ends to form a helical EMI shielding structure that unfolds to an unfolded state and folds to a folded state along its center axis. Here, the plurality of interconnected EMI shielding planes are each angularly offset from each other about the center axis to form a helical structure when in the unfolded state. The EMI shielding panels include an encapsulating layer and/or metallic layer.
