The Laminated Waveguide (LWG) has earned lots of attention recently in its one-layer form referred to as Substrate Integrated Waveguide (SIW). This paper reports on the fabrication and measurement results of a type of LWG, the Grooved Laminated Waveguide (GLWG) which is implemented in Low Temperature Co-fired Ceramics (LTCC). Results are given on the fabrication issues and measurements for GLWG devices realized in one and four LTCC layers, working in four distinct frequency bands; U, V, W and G, i.e. from 40 to 220 GHz.
