Hi all,
With the same setup as i have stated before, I have observed the
pattern by changing the spacing between the 2 antennas. For every 1
wavelength increase in spacing i am abserving one lobe around 90deg.
As the spacing becomes lage multiple of wavelength, the ripples
magnitude increase to greater extent. Can someone explain this. With
the experiment i've done, it indicates that for the spacing of 1
wavelength i get the best pattern without ripples.
