I have hunted them with black powder but not archery. One of my buddies has tried it a few times with a bow. I think your best chance of success is to get one of those Double Bull blinds and set it up on a water hole in the middle of prime antelope country. Put it up a fair length of time in advance so they get used to seeing it. And use a decoy.

It is often easier to get permission to hunt antelope on private land during the bow or black powder seasons - where there would be no way you could get in there during rifle season. Bad news is that, at least here in Colorado, the archery and black powder seasons do not correspond with the rut like the gun seasons do - animals are not as distracted with the mating ritual - but bucks are still vulnerable to the water hole stakeout.
