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: Wearable antenna systems in the form of suspenders are disclosed. Such communications suspenders employ antenna elements having a reduced visual signature while maintaining the load bearing functionality of traditional suspenders. The antenna system communicatively couples to portable radios that operate on different RF frequencies via a communications hub. Some of the antennas elements are dynamically positionable (i.e., swappable, switchable, etc.) on 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. The demountable fasteners couple to the user's garment item (e.g., trousers, shorts, skirts, and similar articles). The straps include RF shielding material positioned to reflect RF radiation that emanates from the antenna elements away from the user. The antenna elements are formed using a conductive composition of fully exfoliated graphene sheets present as a percolated network in a polymer matrix.

Abstract: The instant disclosure seeks to a wearable communications and ballistics protection system that includes a carrier, communications hub, and antenna element(s). The hub is affixed to the carrier and includes an antenna port(s). The antenna element(s) is affixed to the carrier. Each antenna port conductively couples to an antenna element as well as demountably and conductively couples to a portable radio. The carrier holds ballistic plates and is configured to be worn on the user's torso and provide ballistic protection thereto. Antenna elements are formed using a graphene-polymer conductive composition. The carrier includes first and second panels that hold ballistic plates and are pivotably coupled together at a top end. The first and second panels are also laterally held together via demountable fasteners. The antenna elements and/or the panels include EM shielding material to shield the user from EM that emanates from antenna elements.
