Abstract
The present invention concerns a high frequency radiating line for radiating electromagnetic energy in a frequency band and comprising at least one tubular conductor (23) surrounding a longitudinal axis (X) and having a plurality of apertures formed into a series of identical patterns (M1) repeated periodically with a period P along said line, characterized in that, when the operating frequency band is of the type [f.sub.r,(N+1)f.sub.r ], where f.sub.r is a given frequency and N is a positive integer greater than 1, each of said patterns (M1) comprises N apertures 0 to N-1 and satisfying the following equations: ##EQU1## where: the index k is an integer such that 1.ltoreq.k.ltoreq.N-1 and refers to the k'th aperture of one of said patterns (M1),
