Abstract
A printed circuit board comprises a metallic layer (12) cooperating with a metallic plate (26) to form a generally polygonal cross-section (48) of an integral waveguide (46) filled with a solid dielectric layer. The metallic layer (12) is on a substrate (10). The metallic layer (12) has a first strip (14) and a second strip (16) spaced apart from the first strip (14). A solid dielectric layer (18) overlies the metallic layer (12). The solid dielectric layer (18) has a first channel (36) exposing the first strip (14), a second channel (38) exposing the second strip (16), and a land (34) disposed between the first channel (36) and the second channel (38). A metallic plate (26) overlies the land (34), extends through the first channel (36) to the first strip (14), and extends through the second channel (38) to the second strip (16).
