Abstract: A radio frequency transmission arrangement comprises a ground plate having an aperture comprising a slot with an elongate cross-section and substantially parallel sides, and a first and second transmission line. The thickness of the ground plate is greater than a width of the slot. The first transmission line comprises a first elongate conductor on a first side of the ground plate and has an end terminated with a first termination stub. The second transmission line comprises a second elongate conductor on the opposite side of the ground plate and has an end terminated with a second termination stub. The first transmission line is arranged to cross the slot at a point adjacent to the first termination stub, and the second transmission line is arranged to cross the slot at a point adjacent to the second termination stub.

Abstract: An antenna array assembly comprises at least a first and second antenna element, each comprising at least one radiator element in a substantially parallel relationship to a respective ground plate, and an isolator bar disposed between the respective ground plates of the first and second antenna elements, the isolator bar being elongate having a cross-section comprising a T shape, the cross-section being across a long axis. The isolator bar comprises a support bar in contact with the ground plates forming the stem of the T shape, and a cross piece forming the top of the T shape. The cross piece of the isolator bar has a width in the cross-section of at least a quarter of a wavelength at an operating frequency of the antenna array, whereby to provide radio frequency isolation between the first and second antenna elements.
