ABSTRACT:
A low frequency, complementary bowtie antenna structure, including a resistive film, a sheet of silicon impregnated with ferrite material and a sheet of rigid dielectric foam. The film has a linearly tapered resistive coating applied to a surface, and is cut in the shape of a complementary bowtie radiator. A center conductor of a feed coaxial line is soldered to the most conductive section of the resistive material. The outer conductor of the coaxial line is connected to a ground plane. The antenna structure can be used in a conformal, L-band array of bowtie radiators which can be integrated into an X-band array aperture with minimal impact on the radiation and RCS performance of the X-band array.
