d is less than landa/2.
the bandwith is 2 to 6 GHz.
We used switched lines so the same configuration worked for the whole bandwith.
One algorithm worked. We put shifts suchs as: 100, 200, 300, 400, 500,...
In other algorithm, we modulated to 360º and the shifts we put are: 100, 200, 300, 40, 140,...
The algorithm where we modulate doesn't work.
A friend thinks that modulating to 360 is equivalent to reducing the inter-element distance, but I think something we made is wrong. what do you think?
The results were that the pattern was pretty smooth, with the maximum in the right direction, but with no secundary lobes, as if the sum of many grating lobes had happened. In the right pattern, we got 7 secondary lobes, pretty well shaped and with good beamwith and NLS.
hope I have explained my self.
what do you think about modulating the phase shift to 360? It should work fine, right?????
thanks guys
