Special Issue Information

Dear Colleagues,

The design and production processes of an antenna require, as a crucial step, its characterization through suitable measurements. This is a very challenging task, since the antenna characteristics (frequency, electric dimension, far-field angular coverage, environmental conditions, etc.) and the intended application determine the choice of the measurement technique to be used that guarantees the desired accuracy. Antenna measurements can be accomplished either through outdoor far-field (FF) test ranges, or indoor compact ranges or near-field (NF) facilities. The pros and cons of far-field versus near-field test ranges are well known to the antenna measurement community. FF test ranges have the disadvantage that the weather conditions and surroundings (buildings, hills, objects, electromagnetic interference from other wireless networks) can impair the accuracy of the measurements and are usually employed when only the FF pattern in the principal planes is required. Indoor compact range systems retain all the peculiarities of FF measurements, but at a shorter distance and in a controlled environment. To this end, they use a collimating mechanism to create a plane wave in the location of the antenna under test, obtained by using a lens or most commonly a parabolic reflector. Indoor NF test setups are usually used when dealing with antennas working at higher frequencies and complete FF pattern evaluations and polarization information are required, which are obtained by a proper post-processing of the NF data through an NF–FF transformation. Accordingly, antenna measurement is an active field of research, with large industrial impact.

Prospective authors are invited to submit original manuscripts on topics including, but not limited to, the following:

  • Advances in indoor and outdoor test ranges;
  • Advances in far-field, compact, and RCS range measurement techniques;
  • OTA antenna measurements;
  • UAV, drone, and robotic-based measurements;
  • Advances in NF–FF transformation techniques;
  • Innovative NF measurement techniques;
  • Electromagnetic algorithms and data processing;
  • Microwave holography;
  • Phased array testing;
  • Measurement uncertainty analysis;
  • Phase retrieval methods;
  • Probe position correction;
  • Specialized antenna NF measurements;
  • Millimeter-wave and terahertz antenna measurements;
  • Time-domain NF measurements;
  • NF probe design and characterization;
  • Numerical methods related to EM measurements;
  • Measurement standards and laboratory comparisons;
  • Compressed sensing for antenna test applications.

As can be seen, the topics addressed in this Special Issue wholly fall in the scope of Sensors.

Every experimental measurement is affected by random and/or systematic error sources, causing the measurand to have an associated uncertainty quantified in terms of a confidence interval and confidence level. For high-accuracy spherical near-field antenna measurements, there are approximately 20 error sources whose individual contributions to the measurand uncertainty must be estimated for each antenna under test; thus, this uncertainty estimation is a required task in each measurement project. The error sources associated with the mechanical alignment of the antenna under test are of particular importance, not only because the consequential pattern uncertainty differs significantly for different antennas under test, but also because the common practice of experimental uncertainty estimation is very time-consuming with separate uncertainty measurements, thus requiring the antenna under test as well as the measurement facility. We propose a numerical pattern uncertainty estimation for mechanical alignment errors based on a nominal full-sphere measurement without the need for separate uncertainty measurements. Thus, it does not occupy either the antenna under test or the measurement facilities. In addition, numerical uncertainty estimation enables the isolation of individual error sources and their contributions to pattern uncertainties. Full article
