A microwave delay line, which has a periodic geometrical structure involving more particularly the repetition of first and second meshes so that the amplitude of the inverse mode of transmission is reduced compared with that of a helical line, which comprises rods made from a dielectric and good heat conducting material, arranged parallel to the line axis and regularly distributed over its periphery. These rods are equally subdivided into first and second groups, which are regularly distributed over the line periphery. The rods of the first group are brazed to the first meshes of the line and insulated from the second meshes and the rods of the second group are brazed to the second meshes of the line and insulated from the first meshes.
