  "description": "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 ±0.07 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.",
