Radiating cable having spaced radiating sleeves
First Claim
Patent Images
1. Radiating high frequency cable having an inner conductor, an outer conductor and a spacer made of dielectric material disposed and configured so as to establish a concentric relation between the inner and the outer conductors, the outer conductor being constructed to radiate high frequency energy as transmitted through the cable, the improvement comprising:
- an insulative envelope on the outer conductor; and
a plurality of radiating elements made of electrically conductive material and placed on the envelope in axially spaced apart relation to each other, each of the elements having an axial length not larger than half the wavelength of the radiated energy at a particular frequency of a radiated band, the elements having an axial center-to-center distance equal to the wavelength of the energy at said frequency and as transmitted through the cable.

Abstract
A regular, radiating coaxial transmission line is improved by covering it with an insulating coating; similar, cylindrical, radiating elements are equidistantly placed on the line and at a center-to-center distance equal to the wavelength of the center frequency of the h.f. band as transmitted in and through the line.
