Near-field (NF) measurement techniques and the related NF to far-field (FF) transformations
are gaining interest for their ability to allow an accurate evaluation of the radiation …

Emerging 5G and Beyond wireless systems are putting the focus on millimeter-wave (mmW)
and sub-THz antenna systems with multiple beams and a large number of elements yielding …

Single-cut techniques allow for fast antenna characterization by measuring and transforming
to far-field individual pattern cuts instead of the full sphere. The cut fields are expanded in a …

We describe a method to use numerical simulations concurrently with measurements (near-
field data) to characterize the radiation properties of an antenna (far-field) with a strongly …

In this article, we address the problem of reducing the number of required samples for
spherical near-field (SNF) antenna measurements by using compressed sensing (CS). A …

The antenna near-field samples (NFSs) are obtained by a circular array of probes (CAP) in
spherical array sampling systems. In order to reduce sampling time, this article proposes a …

This paper introduces a fast single-cut near-field to far-field transformation method using
amplitude-only data. By measuring the antenna near-field amplitude on two concentric rings …

Die sphärische Nahfeldmessung ist eine etablierte Methode, die vollständige
dreidimensionale Strahlung von Antennen präzise zu charakterisieren. Das Verfahren …

The theory behind spherical near-field antenna measurements places a certain boundary to
the number of samples needed for a complete measurement which, subsequently, sets the …

This work presents a fast Planar Near-Field (PNF) technique for characterizing electrically
large antennas from sparse acquisitions over localized angular domains employing a …
