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.
Abstract:
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.
