Hi all,
I have a problem to firstly understand and secondly solve this problem :
here is the Problem :
Consider three (coherent) antennas variously arranged on the xyplane where each individual antenna radiates an isotropic electric field E(x).
1  Write down an expression for the farfield powerpattern of the antenna array in the xyplane.
2  Configure the phase of each individual antenna in such a way, that the resulting powerpattern of the antennaarray will have a maximum at a chosen angle α .
3  plot the normalised powerpattern as polarplot both in natural and logarithmic scale for at least two different lookangles.
E_{i}(r,t) = E_{0}(x_{i})e^{i(k.r  ωt + kxi sin(θ))}
[/B]
Z = 0
