    • Accuracy evaluation for antenna measurements at mm-wave frequencies 

      Beitrag zu einer Konferenz
      Böhm, Linus; Bögelsack, Frank; Hitzler, Martin; Wiehler, Stefan; Waldschmidt, Christian (Universität Ulm, 2016)
      Measurements of integrated antennas are often cumbersome and erroneous. Inaccuracies of the measurement setup, unknown material parameters, and metal parts in the immediate surrounding of the antenna under test (AUT) cause ...
    • An automated millimeter-wave antenna measurement setup using a robotic arm 

      Beitrag zu einer Konferenz
      Böhm, Linus; Bögelsack, Franck; Hitzler, Martin; Waldschmidt, Christian (Universität Ulm, 2015)
      In order to measure antenna properties precisely at frequencies above 100 GHz, elaborate measurement techniques are required. This is especially challenging for integrated antennas, as probes require a steady, rigid ...
    • Influence of the wafer chuck on integrated antenna measurements 

      Beitrag zu einer Konferenz
      Böhm, Linus; Hehl, Markus; Waldschmidt, Christian (Universität Ulm, 2016)
      For meaningful pattern measurements of integrated antennas the devices, which are required during the measurement process, need to be optimized to influence the measurement results as little as possible. In this paper the ...
    • Probe influence on integrated antenna measurements at frequencies above 100 GHz 

      Beitrag zu einer Konferenz
      Böhm, Linus; Hitzler, Martin; Roos, Fabian; Waldschmidt, Christian (Universität Ulm, 2016)
      When measuring integrated antennas the signal has to be fed to the antennas with wafer probes. Wafer probes are commonly used to contact integrated circuits for on-chip measurements. As integrated radar and communication ...
    • Scattering center determination for integrated antenna measurements at mm-wave frequencies 

      Beitrag zu einer Konferenz
      Böhm, Linus; Waldschmidt, Christian (Universität Ulm, 2017)
      In this paper the results of integrated antenna measurements are analyzed to identify the main reflection locations when measuring with wafer probes. Two different approaches are described and the measurement results for ...
    • The challenges of measuring Integrated antennas at millimeter-wave frequencies 

      Wissenschaftlicher Artikel
      Böhm, Linus; Bögelsack, Frank; Hitzler, Martin; Waldschmidt, Christian (Universität Ulm, 2017)
      The increasing demand for radar sensors and the wide distribution of handheld communication devices push the development of low-cost components with a small form factor. One approach to achieve smaller, low-cost devices ...
