My English might be bad. Please ask me if there is my lack of explanation.
I'm working on the tutorials on Phased Array Antenna(Rectangular). After I finished, I changed the shape type to the circular one(because of my research).
I wanted to change the beam direction like θ=30°,Φ=45°, but I couldn't. I thought the way to do it was to set up the each phase of the elements(in my case, there are 8 elements), but it wasn't.
Does its phase mean "phase difference when excitation is applied", right?
My question is,
- Is there any way to change the beam direction?
- What will happen when I change the phase?
For example, I set up each phase to 0° at first. And I rotated by 30° at each elements in the next Analysis.
As a result, although the shape of the beam had changed, the direction hadn't changed. Why?
