The structure has a dielectric substrate (1L,1U), two principal conductor layers (2L,3L;2U,3U), two rows of conductor groups across the lateral wall (4L,4U), and an auxiliary conductor layer (5L,5U). The two lines of waveguides (6L,6U) are superposed such that one (2L) of the layers (2L,3L) of one (6L) of the lines and one (3U) of the layers (2U,3U) of the other line (6U) overlap one another for defining an overlap part in which a coupling window (7) is formed. |
