    Abstract: Embodiments of the present invention relate to a symmetrical printed radio frequency identification antenna and method of forming a radio frequency identification antenna. In one embodiment, the radio frequency identification antenna comprises a loop element having a plurality of sides. A first conductive element is in electrical communication with the loop element. A second conductive element is in electrical communication with the loop element. The first conductive element includes an integrated circuit pad. The first and second conductive elements extend in opposite directions substantially from a middle portion of a side included in the plurality of sides. The loop, first conductive element, and second conductive element are electrically conductive. The second conductive element includes a quadrilateral portion. The second conductive element has a width that is at least about the length of the side included in the plurality of sides.

    Abstract: Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders may employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system can establish mesh networking communications and communicatively couple to portable radios via a communications device. Some of the antenna elements may be within the communications suspenders. A plurality of straps are pivotably coupled to an intermediate portion at one end and a demountable fastener at the other end that couples to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps may include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements may be formed using a conductive composition that includes fully exfoliated graphene sheets present as a percolated network in a polymer matrix.

    Abstract: 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.

    Abstract: Embodiments of the present invention relate to a graphene-based Rotman lenses and associated methods of formation. In some embodiments, a lens is positioned proximate to a surface of a dielectric plate. In other embodiments, the lens comprises a first lens contour positioned opposite a second lens contour. In certain embodiments, a plurality of first transmission lines extends from the first lens contour and each terminating at a particular first port. In yet still other embodiments, a plurality of second transmission lines extends from the second lens contour and each terminating at a particular second port. In some embodiments, the lens includes a composition having a polymer(s) and a three-dimensional network of individual sheets of graphene positioned within the composition. In certain embodiments, the first port and/or the second port has a width of λ/2 or less.
