Abstract
A radiating coaxial cable comprises an inner conductor, a layer of cellular foam dielectric material surrounding the inner conductor, and a single, continuous, corrugated outer conductor surrounding the dielectric foam layer in direct contact with it. The outer conductor forms at least one row of slots which are configured to produce a radiated field polarized perpendicularly to the axis of the cable to substantially avoid the radiation of a field polarized parallel to the axis of the cable and to provide coupling energy between the interior of the cable and the slots. In this way a substantially constant near-field pattern is produced along the length of the cable across the bandwidth of the cable.
