The only "engineering" antenna Im aware of is called an isotropic radiator.
Build one
and you get a free trip to stockholm.

Subject: [TowerTalk] Engineering antenna
I am interested in looking at the effectiveness of modeling as a true
predictor of feedpoint and loading issues.
In many fields of engineering, there are standard devices used to test.
E.g. dummies in autos for crash tests; I've seen engineering potholes at the
MTS facility in Minnesota; toilet makers use little balls of puddy with a
single string connecting them (guess what those are!) I want to know if
anybody has actually studied antennas.
Specifically, an antenna x' long, y' high, z" diameter and configured thus
and so will yield a feedpoint impedance of R+/-j ohms and exhibit G dB gain
over a iso radiator, etc.? Build a NEC model, build the actual antenna,
measure, and compare. Is there such a thing as an engineering antenna?
Any input is greatly appreciated.
