Enablers for Ambient Services & Systems – 60 GHz Broadband Links
a German BMBF/DLR Project (FKZ 01BU0807)

A German BMBF/DLR project: The work of IMST GmbH comprises various contributions in the areas RF circuit fabrication technology on LTCC, antenna design, and system design (base band and radio channel) for the eventual demonstration of an „In-flight Entertainment“ (IFE) system on board an aircraft as an example of a broadband multimedia application.
In particular, a LTCC substrate for and the housing of the demonstrator’s 60 GHz-front end will be developed together with suitable antennas and cover 7 GHz of unlicensed bandwidth there. Final goal is to explore the feasibility of combining both the RF chips and circuitry and the antennas on the very same LTCC module. The 2x1 symmetric differential antenna has a higher gain than 8 dBi over 8 GHz bandwidth – feeded at chip-pad. In the area of base band signal processing, the applicability of systolic arrays as circuit elements in digital signal processing will be evaluated and some exemplary algorithms will be implemented as parallel structures.
There are 3 generations of LTCC-boards and chips designed and manufactured as well.
As a fundamental prerequisite for the design of the whole system, the characteristics of the radio channel at 60 GHz inside an aircraft cabin will be investigated and modeled.
The outcome of this subproject has further areas of application, like wireless telemetry & control or sensor networks.
