Abstract :
In this paper, a fabric equiangular spiral has been shown to perform comparably to a conventional copper-clad laminate spiral of the same design. Although the fabric antenna was supported by a fairly lossy substrate, and the conductivity of the arms is less than that of copper, the effects of these loss mechanisms appear to be negligible. It should be noted that the balun, which extends the length of the arms, is characterized by a higher conductivity than the conductive fabric and may be mitigating possible losses. Planned future work includes development of a fabric balun structure in order to enhance flexibility and to implement fabric interconnects
