How do USB wireless N adapters get by with one antenna connector?

After reading a current post, and looking at a wireless N PCI card with the usual 2 or 3 antennas, and then looking at a USB N adapter, I have to ask how the USB adapter gets by with one antenna.

To go directional antenna with N obviously you don't want multiple yagi's etc to deal with, so the USB adapter appears to have a distinct advantage in this aspect.

So how does the USB adapter do it?
