Comparison of antenna parameters of R-/S-band standard gain antennas

A comparison of antenna parameters (i.e. antenna gain, radiation pattern and reflection coefficient) for R-band (1.7-2.6 GHz) and S-band (2.6-3.95 GHz) standard gain antennas has been performed between Korea Research Institute of Standards and Science (KRISS) and seven domestic participants including private companies and public organizations. Its purpose, as a proficiency test program of the `Antenna Measurement Club´ of KRISS, was to check equivalences in antenna parameters measurements, particularly in R-/S-band, between KRISS and participants to support antenna manufacturers and end users in Korea. This comparison uses two traveling standards (i.e. R-/S-band pyramidal standard gain horn antennas) and measurement parameters are the power gain, radiation pattern and reflection coefficient of the traveling standards. Gain comparison method and extrapolation method are used in this comparison.
