The thickness of the ground plate (t) is greater than a width of the slot (w). The aperture (14, 15a, 15b) is partially filled with a solid dielectric material and partially filled with air. The first transmission line comprises a first elongate conductor (12) on a first side of the ground plate (13) and has an end terminated with a first termination stub (11). The second transmission line comprises a second elongate conductor (17) on the opposite side of the ground plate and has an end terminated with a second termination stub (18). The first transmission line is arranged to cross the slot at a point adjacent to the first termination stub (11), and the second transmission line is arranged to cross the slot at a point adjacent to the second termination stub (18).
