Waveguide with signal track cross-over and variable features

摘要

A waveguide structure and a method of forming a waveguide structure is disclosed. The waveguide structure includes at least three dielectric layers juxtapositioned together such that two layers are positioned as outer layers. At least two intermediate signal path layers are positioned between respective dielectric layers. The outer dielectric layers each include a ground layer to form opposing ground planes. A controlled impedance signal track is formed at each intermediate signal path layer and a plurality of conductive vias interconnect the ground planes.
