Abstract:
1. A conformable wide-band antenna apparatus comprising: a conformable spiral antenna element; a conformal ground plane; and a solid disc-shaped conformal noise suppression sheet interposed between said conformal spiral antenna element and said conformal ground plane, said conformal noise suppression sheet having a magnetic permeability (mu) in the range of about 40 at 1 MHz to about 100 at 1 MHz, wherein said disc-shaped conformal noise suppression sheet is surrounded by a co-planar ring-shaped conformal noise suppression sheet having a magnetic permeability (mu) in the range of about 40 at 1 MHz to about 100 at 1 MHz and of a different magnetic permeability than the magnetic permeability of said disc-shaped conformal noise suppression sheet; and wherein said conformable spiral antenna element is spaced from said conformal ground plane by a spacer.
