Hi everyone,

I have 2 questions and I hope you can guide me through:

1. I have to do a simulation of a phased array patch antenna. I believe the best settings in terms of boundaries, is to use PBC and not Unit Cell. Please correct me if I'm wrong. (I have tried to use unit cell, but, for example, if I want to see the grating lobes while changing the scan angles, I can't see them and if you can give me an explanation on this matter it would be great). While with the PBC, everything is working as expected
2. I was trying to use the unit cell boundary condition, because I need to analyse the triangular lattice of an array, and with the unit cell BC, I was able to select the angle in the grid, like 60 degrees. With the periodic boundary conditions, however, I do not have this option and I'm trying to find a way to simulate a unit cell of an array with triangular lattice. Do you happen to know how can I simulate this scenario?

Thank you
