    "title": "Data for \"Enhanced Gain Extrapolation Technique: a third-order scattering approach for high-accuracy antenna gain, sparse sampling, at Fresnel distances\"",
    "description": "In this paper we describe an enhanced three-antennagain extrapolation technique that allows one to determine antennagain with significantly fewer data points and at closerdistances than with the well-established traditional three-antennagain extrapolation technique that has been in use for overfive decades. As opposed to the traditional gain extrapolationtechnique, where high-order scattering is purposely ignored soas to isolate only the direct antenna-to-antenna coupling, we showthat by incorporating third-order scattering the enhanced gainextrapolation technique can be obtained. The theoretical foundationusing third-order scattering is developed and experimentalresults are presented comparing the enhanced technique andtraditional technique for two sets of internationally recognizedNIST reference standard gain horn antennas at X-band and Ku-band.We show that with the enhanced technique gain values forthese antennas are readily obtained to within stated uncertaintiesof \u00b10.07 dB using as few as 10 data points per antenna pair,as opposed to approximately 4000 -to- 8000 data points per antenna pairthat is needed with the traditional technique. Furthermore, withthe described enhanced technique, antenna-to-antenna distancescan be reduced by a factor of three, and up a factor of six insome cases, compared to the traditional technique, a significantreduction in the overall size requirement of facilities used toperform gain extrapolation measurements.",
