Ed,Thanks for the response.I am looking to measure the gain of an antenna in
order to calculate EIRP of a product.As far as the 2D vs. 3D, I don't have any
values. I was hoping some one who has made measurements using both 2D and 3D
would be able to comment how much better 3D is over 2D when considering peak
gain.
I appreciate your feedback, thanks.
Stephen

{}#yiv3080917348 Stephen: There are a number of ways to measure gain, with the
basic one being a comparison to a theoretical isotropic radiator (yielding a
gain number in dBi). However, the antennas used for EMI and compliance testing
are usually used in the near field, where the standard you are testing to
defines the acceptable measurement distance and styles of antennas. Thus, there
is often a preferred gain measurement technique defined by the standard you are
working to. In regard to what you told us, what is 2D & 3D (dimension) gain?
And what is peak gain? What standard is defining these terms? Ed Price

which standard is used for measuring antenna gain?Are 3D antenna gain
measurements typically different than 2D with regards to peak gain? If so,
what's typical delta, 0.5dB or less? Regards,Stephen-
