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: Embodiments relate to a communications node that includes an interfacing plate assembly; an antenna assembly; a board mounting assembly; a housing; and an enclosure. The housing includes the antenna assembly and the board mounting assembly. The enclosure is a rigid, open ended, sleeve structure that selectively receives the housing and thereby encloses the antenna assembly and the board mounting assembly therein. An interfacing plate assembly is positioned at a second end. The interfacing plate includes an input device coupled to the control circuit that receives user operational input. The antenna assembly includes an antenna frame that includes the antenna elements and orients the antenna elements in each nodal cardinal direction. The board mounting assembly includes the communication device and the control circuit that are positioned proximate to a plate. The plate is coupled to the first end opposite the interfacing plate and thermally coupled to the control circuit.
