Abstract:
1. A composite woven fabric, comprising: quartz glass fibers including quartz glass each having a relative dielectric constant of 3.9 or less at 1 MHz and a relative dielectric constant of 4.0 or less at 1 GHz and the quartz glass fibers each having a dielectric loss tangent of 1.5×10 polyolefin fibers consisting of one of polyethylene fibers, polypropylene fibers, or polystyrene fibers, and wherein the polyolefin fibers each have a relative dielectric constant of 3.0 or less and a dielectric loss tangent of 3×10 wherein a ratio of the quartz glass fibers to the composite woven fabric is 10 vol. % or more and 90 vol. % or less.
