Abstract (en)
[origin: US5291164A] 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 (fr,(N+1)fr), where fr 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: (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) where: the index k is an integer such that 1<=k<=N-1 and refers to the k'th aperture of one of said patterns (M1), zk is the distance between said k'th aperture and first aperture (F0) of the pattern, ak is the polariability of the k'th aperture, ao is the polarizability of the first aperture, (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) where E(x) designates the integer part of x, pk is an integer such that 1<=pk<=N+1, said integers pk being pairwise distinct, such that pk<pk+1, and different from p' and p".
