array antenna+simulation

I have a 3-D vivadi antenna element in HFSS, contained in cubic air box,
waveport excitation. want to extend to 16X16 array simulation. From the help document, I understand I gotto set up some master/slave boundaries condition for the antenna cell. But I have no idea how to do that. could somebody please share your experience with me or show me
some example?

Thanks a lot,
