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.
