Efficient Modeling and Optimization for the Design of Compact and Innovative Multilayer Slot Antennas – MOCACCINO

Submission summary

The MOCACCINO project is proposed within a social and economic context characterized by a significant increase of communication needs. In particular, we observe in particular the rapid deployment of new infrastructures, as well as the densification and ramping-up of existing ones. All these evolutions tend to increase connectivity and information circulation rate between users, thus benefiting multiple economic sectors (healthcare, mobility, industry, security etc.). This requires an optimal usage of both physical space and frequency spectrum. To that end, it is crucial to have at our disposal planar antenna systems with high efficiency, directivity and wide-band operability. These antennas ensure both low consumption communications and high data-rates. Current and future SATCOM systems constitute an illustration of these demanding requirements cohabitation. One can also cite terrestrial infrastructures for 5G+ and 6G.

The Numerical developments proposed in MOCACCINO aim at supplying powerful tools for design and optimization of very compact and complex antennas, exhibiting high radio-frequency performance level and energy efficiency.
This project propose to increase the maturity level of design and optimization tools initially developed in the Fast-HEM-3DSIW (ANR-16-ASTR-0001), overcoming the limitations of general-purpose commercial software. These tools will allow for the efficient and fast analysis of planar systems with very high complexity in order to meet application needs. Indeed, the high performance level relies on the fine optimization of the numerous geometrical degrees of freedom offered by multi-layer printed circuit board technology, the proper choice of materials, as well as the modeling of elements in the near-field of the antennas such as superstrates (radome, lense, frequency selective surface, metasurface).

In parallel, this project propose to continue the development of multilayer corporate feed networks in printed circuit board technology, such as introduced in the initial ASTRID project in order to significantly increase gain frequency stability of slot array antennas. Finally, this numerical tool will provide better design capability for other microwave components (feed networks, filters, coupler etc.).
