Hello,
I have modeled a linear array of dipoles along the X-axis (all dipoles being oriented along the Z-axis). All dipoles have been excited uniformly using voltage sources. According to the theory, the main beam can be steered if a progressive phase shift could be applied to the input. So, to achieve a 30 degree beam scan, I have assigned the phase (in the phase column of the voltage source dialogue box) to be 0, 30, 60, 90, ..., 720 starting from the first to the 25th dipole element. For this configuration it is expected to get the main beam at 120 deg, but I could get the main beam at 99.5 deg (I have attached the FEKO file here). What am I doing wrong? How can I get the desired scanning? Please suggest.
Thank you in advance.
