Hi Stephen,
Lots of questions are required to answer your question with any accuracy. I assembled a system to do spherical patterning to our product antennas above 1 GHz, so I have some exposure to the problems. A few of those questions: - Are these product antennas rather than well behaved metrology type antennas? - Are they independent or built into a product? - Is the transmitting device unique or intended to be used as a module in many products? - What is the frequency range to be investigated? If I can make a guess, my interpretation of 2D would be planar pattern cuts on each of three orthogonal axes vs 3D being an altitude/azimuth pattern measured at some spherical radius. Just to be even less helpful than I have been, there are IEEE, ANSI and IEC standards that don’t always agree and need more information to pick and choose from. Keep at it!

Are 3D antenna gain measurements typically different than 2D with regards to peak gain? If so, what's typical delta, 0.5dB or less?
