Embodiment 100
[0031] The radiating elements of embodiment 100 are elongated slots in the outer conductors 114, 124 that are perforated through, and have a main direction of elongation that causes the slots to radiate. The main direction of extension in which the slots radiate differs between different types of cables: in coaxial cables, as shown in the figure, the main direction of extension should not coincide with the main extension length of the cable. In waveguide, or microstrip, or stripline structures, the main direction of elongation of the slots can coincide with that of the structure or cable and still radiate. Regarding the precise shape of the radiating elements, it should be noted that although in the figures they are shown as elongated slots and are referred to as such in the description, the radiating elements can be chosen from a number of different types of perforations in the outer conductor shape, although preferred embodiments comprise elongated rectangular or oval slots....
Embodiment 200
[0035] The radiating element of embodiment 200 is also an elongated slot in the outer conductor 214 , 224 , 234 , 244 through the perforation and has a main direction of elongation that causes the slot to radiate. Preferably, the shape and distribution of the perforations of all cables are approximately equal.
[0036]Furthermore, as shown in Fig. 3a, the cables 210, 220, 230, 240 are arranged within the bundle such that the radial positions of the cables 210, 220, 230, 240 alternate in the direction of longitudinal extension. The alternation of the radial positions of the cables 210, 220, 230, 240 may be formed by folding at least one cable present at a first side of the bundle to a second side of the bundle. Thus, by periodically changing the location of each cable 210, 220, 230, 240 in the section of the bundle, at all locations along the extension of the bundle, the occurrence of all cables 210, 220, 230, 240 is equal. Furthermore, the alternation of the radial positions...
