Embodiments of a radio frequency feedline structure. A first printed circuit board (PCB) includes upper and lower metal layers and at least one cutout defining an upper portion of an open channel. The upper and lower metal layers are electrically connected by vias on opposite walls of the cutout. A second PCB includes upper and lower metal layers and elongated slots defining a suspended signal path within the open channel. The upper and lower metal layers are electrically connected by vias. A third PCB includes upper and lower metal layers and at least one cutout defining a lower portion of the open channel. The upper and lower metal layers are electrically connected by vias on opposite walls of the cutout. Respective upper and lower ground planes are electrically connected to the upper metal layer of the first PCB and the lower metal layer of the third PCB.
