In this paper we describe an enhanced three-antenna
gain extrapolation technique that allows one to determine antenna
gain with significantly fewer data points and at closer
distances than with the well-established traditional three-antenna
gain extrapolation technique that has been in use for over
five decades. As opposed to the traditional gain extrapolation
technique, where high-order scattering is purposely ignored so
as to isolate only the direct antenna-to-antenna coupling, we show
that by incorporating third-order scattering the enhanced gain
extrapolation technique can be obtained. The theoretical foundation
using third-order scattering is developed and experimental
results are presented comparing the enhanced technique and
traditional technique for two sets of internationally recognized
NIST reference standard gain horn antennas at X-band and Ku-band.
We show that with the enhanced technique gain values for
these antennas are readily obtained to within stated uncertainties
of ±0.07 dB using as few as 10 data points per antenna pair,
as opposed to approximately 4000 -to- 8000 data points per antenna pair
that is needed with the traditional technique. Furthermore, with
the described enhanced technique, antenna-to-antenna distances
can be reduced by a factor of three, and up a factor of six in
some cases, compared to the traditional technique, a significant
reduction in the overall size requirement of facilities used to
perform gain extrapolation measurements.
