Purpose and goal

Ericsson, Saab and Chalmers have jointly investigated a building practice for future of multi-antenna-mm-wave systems. The results (see attached final report) show that it has the potential to provide a compact and high-performance integration of gallium nitride, silicon CMOS and antenna. This opens up completely new opportunities to realize advanced millimeter wave communication and sensor systems that combines high power, high efficiency, high functionality, and low cost with a small size

Expected results and effects

The building practice used in today´s communications and sensing systems cannot easily be adapted to the requirements of mm-wave / multi-antenna- applications. Extensive theoretical and simulation-based studies were performed as part of the feasibility study. The results show that the proposed building practice has great potential to meet the requirements of future systems. Further studies are required to evaluate its practical limits, and answer the questions that remain before commercial exploitation of the concept.

Planned approach and implementation

The feasibility study benefited from the parties´ unique background in high power GaN processes (Chalmers), production processes for mm-wave frequencies (Ericsson) and building of large antenna systems (Saab). In the attached final report we describe how fundamental issues regarding materials and antenna, specifications, and construction of signal transmissions have been addressed and answered. The partners have proposed a model contract for protection and use of IP in the coming project. The answers have laid the foundation for the submitted full project application.
