Abstract
A leaky cable with a central conductor, and an outer conductor having a rectangular cross section surrounding the central conductor. The outer conductor has a first and a second surface parallel to each other, and at least one slot row formed in at least one of the first and second surface. The slot row is formed in a first direction of the outer conductor and includes a plurality of slots each configured to form a leaky electromagnetic field. An insulator is disposed between the central conductor and the outer conductor. The width of the rectangular cross section in a direction parallel to the first and second surfaces is less than half of a wavelength of an electric signal transmitted through the leaky cable.
