TPMS (Tire Pressure Monitoring Systems) are required to provide high efficiency RF transmission, to be realized using components with reduced overall dimensions. Then, the design of TPMS antennas is a critical task, to be performed with accurate optimization activities based on intensive experimental development. In this field, MID technology can provide a strong strategic advantage since it can reduce the overall dimensions integrating different components and functionalities and, at the same time, permitting seamless fast prototyping, and customization, of different variants of the antenna layout. In this paper it will be presented the integrated design and development (and the methods adopted) of a novel TPMS RF transmission unit, realized with LDS technology. In this activity, the design engineers used synergically several software tools to simulate and evaluate concurrently all the different problems involved. The component geometries were designed in order to fulfil the structural and mechanical requirements, the molds were concurrently developed and the injection moulding process accurately simulated to validate the final shapes. At the same time, different design variants of the antenna were developed with intensive numerical simulations. A prototype mould was then quickly realized and specimens produced where, with LDS technology, the antennas lay out variants were manufactured. Several experimental testing on such prototypes were then performed in order to tune the 3D electromagnetic field simulation parameters (and be then able to perform further optimization studies on virtual prototypes). Finally a fast optimization of the antennas components was realized and the manufacturing processes tuned. Such activities were jointly realized by DIMEC, Mechanical Engineering Department of the University of Modena researchers and Kontek Comatel R&D team
