Abstract
A radiated mode coaxial cable comprising an outer conductor provided with a periodic aperture array, comprising a plurality (n) of apertures or aperture sets, repeated along the length of said outer conductor whereas a constant spacing s separates the left end of the first aperture of one array and the left end of the first aperture of a next array, wherein each array comprises at least 10 apertures or aperture sets, whereas the global length L (in mm) of the apertures or aperture sets is larger than (10D/n)where D is the diameter of the cable (in mm) and whereas the aperture spacing (d) in between two successive apertures or aperture sets is larger than 1.5w where w is the aperture width in the cable axis direction, and wherein the spacing s between two successive aperture arrays is selected so that λ/(√ε−0,866)<s<λ/(√ε−1), where λand λare respectively the upper and lower limits of the optimal wavelength range the radiated mode coaxial cable is designed for and where εrepresents the relative dielectric constant of the radiating cable.
