This is real-world data...
I had the impression, though, that Directivity was simply a measure of the radiation in a certain direction compared to an average radiation intensity. Shouldn't that be completely described by the radiation pattern, assuming I choose my 'average radiation' to be...
I am extremely new to working with antennas. All of my training comes in physics, which you'd sure think would help out at a time like this -- so I feel like I'm back in graduate school here...
I have a specific 1D Array of data showing an antenna pattern measured from -90 to +90 degrees...
