While this discussion appears to have veered off into a discussion of patch arrays, perhaps it's worth commenting that stress dishes can be made very transportable.
About 15 years ago, Al Katz, K2UYH, described a simple stressed offset stressed dish antenna in the 432MHz and Up Newsletter using - from deep memory! - 6ft ribs. He used sucessfully that for a 1296MHz EME portable operation from somewhere in the the Carribean in which he ran relative QRP, possibly only around 100W, and CW. I suspect that would scale to a collapsible 10GHz antenna without too much trouble.
