Workshop 1

Post processing techniques in 5G, Automotive & Space antenna measurements

Abstract

This course is a fast pace introduction to modern applications of post-processing techniques to exploit the antenna measurement results. Nowadays, the use of information from antenna under test, antenna measurement system and electromagnetic measurements results allow the improvement of those results for:

  • -    Extraction of electromagnetic sources in the antenna surface.
  • -    Detection of errors in antenna design.
  • -    Improving measurement results cancelling echoes, leakage, noise...
  • -    Extrapolating the radiation pattern to unmeasured angles.
  • -    Combination of measurements and simulations to emulate the effect of the environment.

Following a brief introduction to near and far field antenna measurements theory, the course will focus on these techniques. The second part of the course will be the explanation of the following techniques:

  • -    Time gating techniques.
  • -    Extraction of Equivalent sources through inverse electromagnetic problems.
  • -    Use of holographic techniques for extracting equivalent currents on a surface.
  • -    Filtering of measurement results using spherical or cylindrical near field modes expansion.

The third session will deal with different applications of those techniques. In this section, applications for BTS antennas, automotive measurement, RADAR systems, satellite antennas will be shown.

The course outline is:

  • ・  Theory and application of far-field and near field antenna measurements.
  • ・  Equivalent currents using integral equation and holographic techniques.
  • ・  Time domain and time gating techniques.
  • ・  Spherical and Cylindrical modes expansion and filtering of spurious signals.
  • ・  Application in telecom, satellite, automotive and defense measurement scenarios.
