Sub-Contract: Contributions of TU Ilmenau to EASY-A

At Ilmenau University of Technology, the Institute for Information Technology, in co-operation with the Institute for Micro- and Nanotechnologies, contributes to the project EASY-A as a subcontractor of IHP GmbH, Frankfurt (Oder), and IMST GmbH, Kamp-Lintfort, and MEDAV GmbH, Uttenreuth, to the development of the VHR-E demonstrator. The contributions, summarised under the acronym AIRFUN

Antenna Concepts:

  • Design and prototyping of patch antennas on LTCC substrates
  • RX and TX antennas with gain characteristics tailored to the envisaged VHR-E-applications
  • Designs with balanced and unbalanced feeding lines
  • Antennas for UHR-C applications can be derived, if identical frequency, bandwidth, and gain specifications as for the VHR-E designs apply
  • Implementation of a multichannel sounder system with 7 GHz of real-time bandwidth (MEDAV GmbH)
  • Conduction and evaluation of wave propagation measurement campaigns for VHR-E scenarii

Packaging and Antenna Implementation:

  • Evaluation of different LTCC and coating materials at 60 GHz
  • Integration of MMICs, feeding and matching structures, and antennas on a common LTCC substrate
  • Implementation and evaluation of MMIC assembling technologies (flip-chip, chip-and-wire, gluing, chip coating etc.)

Baseband architecture und implementation:

  • Characterisation and modeling of nonlinear distortion in the power amplifiers of the VHR-E demonstrator system
  • Optimisation of baseband signal processing to minimise the effect if nonlinear distortion (single carrier modulation, cyclic prefix, frequency domain processing, iterative (Turbo-) detection)
  • FPGA-implementation in extension of OFDM-baseband platform of IHP

System Integration / Demonstrators:

  • Antenna implementation for the VHR-E demonstrator (number of modules in budget plan corresponds to AIRBUS demonstrator)
  • Simulation and measurement of antenna modules (also modules with IF-interface)
