Thanks for the papers - a quick skim through reveals that they are using a 60 GHz transceiver system from 'Silicon Image'. The company's website (
http://www.siliconimage.com/solutions/wireless/) alludes to the capabilities of their transceivers:
"Featuring low-cost standard CMOS fabrication processes, embedded on-chip antennae, and proprietary
beam-forming algorithms...", and
"...integrates a 60GHz RF transceiver, baseband processor, and embedded
antenna array...", so yup - I'd suspect phased array beamforming - steerable via the GUI so that a "beam" could be "locked" "straight" someplace...?
Alas they don't give much away on the website and make mention of non-disclosure agreements to gain access to anything else.
Designing planar phased arrays with patch antennas is a well worn path, so you shouldn't have any trouble Googling up an information storm if that's what you're looking for
