As technology changes, new and different techniques for measuring and
characterizing antenna performance need to be considered. This paper
examines how a new generation of network analyzers can be utilized in
antenna measurement configurations to make fast, accurate, and reliable
measurements. The paper will list and explain the features of Agilent’s new
PNA series of network analyzers that are particularly well suited for antenna
and Radar Cross-Section (RCS) measurements. The new PNA series network
analyzers are compared to the 8530A microwave receiver to differentiate
and contrast the two instruments in antenna/RCS configurations. The
primary information in this paper will be the configuration diagrams for the
PNA in a variety of antenna test configurations such as near-field, far-field,
radar cross-section, and compact ranges. Important technical information
that needs to be considered for each of the antenna test configurations
utilizing a PNA will also be discussed. Typical performance specifications of
the PNA and measurement system when used in an antenna/RCS configura-
tion will also be presented. A summary of the advantages and disadvantages
of the new performance network analyzers are presented to allow antenna
test professionals to evaluate this new product for their antenna test
configurations.
