A Radio Frequency, “RF”, component and a method of making the same. The component includes a first electrically conductive signal member for conveying an RF signal and a second electrically conductive signal member for conveying an RF signal. The component also includes a barrier located between the first signal member and the second signal member electromagnetically to shield the first and second signal members from each other. The barrier includes a first row of electrically conductive shielding members spaced apart along a longitudinal axis of the first row, and a second row of electrically conductive shielding members spaced apart along a longitudinal axis of the second row. Each shielding member includes a polyhedron. The shielding members of the first row are offset with respect to the shielding members of the second row to prevent a direct line of sight between the first signal member and the second signal member.
