: A measurement method developed to extract the three-dimensional (3D) antenna gain patterns of high-frequency (HF) antennas is presented. The method employs a full hemispheric field probe measurement of an HF antenna on an outdoor antenna pattern range. A calibration method involving both simulation and measurement is used to transform antenna probe measurements into electric field quantities. The subsequent near-field electric field is extrapolated into the far field using an established near-field/far-field transformation method.
