This paper reports on the results of the design and manufacturing of straight sections, tees, bends and loads in a Grooved Laminated Waveguide (GLWG) topology. These devices, intended for the U-, V-, W-and G-band, are fabricated in Low Temperature Co-fired Ceramics (LTCC) technology using the low relative permittivity tape, ESL41110, from ElectroScience Laboratory. Measurements ranging from 40 to 170 GHz prove the concept of grooved laminated waveguides.
