Abstract
A waveguide comprises an inner conductor arranged in a first layer, a pair of outer conductors comprising a first outer conductor and a second outer conductor, and a pair of slotted shields comprising a first slotted shield and a second slotted shield. The first slotted shield and the second slotted shield are arranged in a second layer with a spacing in between to form a section of a ground shield, wherein the second layer is parallel to the first layer. The first slotted shield is connected to the first outer conductor and the second slotted shield is connected to the second outer conductor.
