In today’s digital society, interest in Communicating Objects (OCs) is growing because of the many remote services they offer such as control, control, survey, tracking, diagnosis and sharing, spread over multiple applications (domotics: access control, logistics: stock management, climate: temperature/humidity regulation, e-health: diagnosis and follow-up, etc.). With the advent of new technologies such as LoRA and SigFox, dedicated to low-throughput OCs (meter reading, garbage filling level, etc.) and the effective coverage of all of France by telecom operators, the Internet of Things (IoT) is thus starting its flight to a gigantic interconnection network of all OCs, not only in France but also in Europe (Germany, United Kingdom, etc.) and beyond. Today, the global IoT market is estimated at nearly 1.2 trillion dollars for nearly 18 billion objects by 2022 with double-digit annual growth. This dramatic increase in the number of COs poses the problem of their food and energy optimisation in a European context of sustainable development. This problem is all the more striking as current emerging technologies at lower energy costs such as ambient energy recovery (solar, electromagnetic, vibration, thermal, etc.) for COs are still in progress. On the other hand, most objects like sensors need to be miniaturised to facilitate their integration and mobility in their measurement environment in a non-invasive way. In practice, a reduction in size always leads to a decrease in performance (scope and sensitivity). This physical limitation is accentuated by the fact that the applicable standards, in particular EN 300 220/302 719, drastically limit the output levels. In addition, external factors inherent in the propagation medium (individuals, furniture, vegetation, walls, etc.) degrade the signal by attenuating and adding parasites. The challenge of innovation around CBs, particularly in the emission/reception organ, is therefore essential and requires new design approaches that simultaneously integrate performance, size and consumption constraints.This project provides a response to this need for innovation by specifically targeting the development of new two-directional compact active antenna architectures incorporating a voltage amplifier directly placed in their geometries. The expected performance corresponds to an increase in scope and sensitivity that can lead to improved performance resulting in 50 % energy saving and 50 % reduction in the cost and size of the radio infrastructure for the same quality of service. These benefits will enable: to NXP to gain a major competitive advantage over its competitors and to consolidate its 5G development activities at the Caen site, an increase in the visibility and visibility of the territory for ICT, and finally, a strengthening of the industrial ecosystem and regional collaborations.
