In this paper we present the usage of low temperature co-fired ceramics (LTCC) technology for 79-GHz automotive short-range radar application. Normally, for a radar system the size of the RF-frontend is mainly determined by the antenna aperture. As the working frequency shifts from 24 GHz to 79 GHz, the antenna aperture reduces enormously (as well as the overall-size of the RF-frontend), which also reduces the price difference between the RF-frontends realized on LTCC and on the traditional organic substrate. Further, LTCC offers an extra degree of freedom for designing vertical parallel-feeds for wideband applications. Complex structures like laminated waveguide can be used for a highly integrated RF-frontend solution. In this work, special attention was paid on the material properties, the antenna, the design concept, the process for the outside metallization layers, the solder mask, and the integration possibility. To showcase the result, a 79-GHz LTCC RF-frontend combined with a monolithic microwave integrated circuits is demonstrated with measurement results.
