Dear Alto64,
just to open the discussion and to check the validity of our codes, I just propose a configuration to be evaluated: at the beginning, we can analize
a planar array of 2 x 2 at 1.5 GHz, equally-spaced 0.7 lambda along x and y axis of a radiator whose pattern is cos(x).
let's compute:
Total Pattern on fi =0° and 90°, Directivity, nulls position.
Then we compare our results.
That's my idea, if you want to change the layout, let me know it ok?
Hope it can give us some help, ideas and interest to all the other people joining the section.
Regards
Lupin
