The article explains how to test antennas with a network analyzer. It differentiates the scalar vector analyzer and vector network analyzer (VNA) and discusses the S-parameters as basis of calculations in the VNA. Important factors are considered to depict the condition of an antenna system and techniques used to characterize an antenna system are discussed. Graphs illustrate the frequency domain and wideband time domain voltage standing wave ratio (VSWR) of a frequency modulation (FM) antenna.
