This paper presents the electromagnetic modeling and design of substrate integrated waveguides (SIW) up to W band (75 - 110 GHz) for Low-Temperature Co-fired Ceramics (LTCC) technology. The commercial software package CST Microwave Studio was used to optimize a coplanar waveguide (CPW) to SIW transition. Two test structures with two CPW to SIW transitions were designed, fabricated and measured up to 110 GHz. The comparison between simulated and measured data for the test structures shows a good agreement. The effective permittivity was extracted from both simulated and measured data and show good agreement
