Effective spherical near-field (SNF) test time reduction approaches are presented for wireless base station antennas that have widely differing beamwidths in the azimuth and elevation planes. The geometry of these antennas allows for the optimization of the SNF angular sampling density by allowing a lower sampling density along one of the acquisition axes. This is validated experimentally and shown to reduce the SNF test time significantly without degrading the measurement accuracy.
