    "In this paper we describe an enhanced three-antenna\ngain extrapolation technique that allows one to determine antenna\ngain with significantly fewer data points and at closer\ndistances than with the well-established traditional three-antenna\ngain extrapolation technique that has been in use for over\nfive decades. As opposed to the traditional gain extrapolation\ntechnique, where high-order scattering is purposely ignored so\nas to isolate only the direct antenna-to-antenna coupling, we show\nthat by incorporating third-order scattering the enhanced gain\nextrapolation technique can be obtained. The theoretical foundation\nusing third-order scattering is developed and experimental\nresults are presented comparing the enhanced technique and\ntraditional technique for two sets of internationally recognized\nNIST reference standard gain horn antennas at X-band and Ku-band.\nWe show that with the enhanced technique gain values for\nthese antennas are readily obtained to within stated uncertainties\nof \u00b10.07 dB using as few as 10 data points per antenna pair,\nas opposed to approximately 4000 -to- 8000 data points per antenna pair\nthat is needed with the traditional technique. Furthermore, with\nthe described enhanced technique, antenna-to-antenna distances\ncan be reduced by a factor of three, and up a factor of six in\nsome cases, compared to the traditional technique, a significant\nreduction in the overall size requirement of facilities used to\nperform gain extrapolation measurements."
