Abstract
A radiating cable is constructed from an inner conductor and a concentric outer conductor being separated from each other by a dielectric spacer; the outer conductor has openings of similar size and configuration but their density varies periodically in axial direction. In one example, the openings are arranged in circumferential rows and axial rows, the number of openings for circumferential row varies periodically in axial direction. In another example, a single axial row has its openings spaced in a periodically variable spacing.
