Yes this can be done. First, if all antennas are the same,
you only need to build one and then use the GM card to create a linear
equally-spaced array or the GR to create an equally-spaced circular
array. The exception to this is that each feed segment must be
explicitly modeled in order to attach the sources.
A good exercise is to start with a classical equally-spaced
linear dipole array out of a text book. Build the dipoles and then
specify a source for each dipole. Probably the most overlooked item
is the fact the most text books specify currents at the feeds rather
than voltages that NEC uses. I do not readily recall the method of
creating current sources but it is easy and numerous readers can give
you inputs on this.
Good luck.
