WIDE-BAND CONFORMAL COAXIAL ANTENNA

Abstract:

Disclosed is a wide-band conformal coaxial antenna conformal to a surface that comprises an inner conductor, an outer conductor, and a dielectric layer. The inner conductor extends towards the surface from a coaxial input below the surface and the outer conductor surrounds the inner conductor extending from the coaxial input to the surface. The dielectric layer is between the inner conductor and the outer conductor. The inner conductor has a first inner conductor diameter at the coaxial input and a second inner conductor diameter at a distal end of the inner conductor at or proximately below the surface. The inner conductor forms an inner conductor surface at the distal end of the inner conductor and the second inner conductor diameter is larger than the first inner conductor diameter. The outer conductor has a first outer conductor diameter at the coaxial input and a second outer conductor diameter at the surface. The second outer conductor diameter is larger than the first outer conductor diameter.
