Abstract

1,272,878. Aerials; radio signalling. SUMITOMO ELECTRIC INDUSTRIES Ltd. 16 Nov., 1970, No.54446/70. Headings H4A and H4L. A leaky coaxial cable is provided with an array of radiating slots along its outer conductor and may be used, for example, to enable communication with a vehicle running beside it. In order to compensate for attenuation in the wave transmission direction at least one of the following slot characteristics is changed gradually and successively, i.e., shape, dimensions, angle made with the axis of the cable. The change or changes may occur between successive slots, or between successive groups of slots.
