A recent article, posted at <a href="http://m.mwrf.com/">Microwaves &amp; RF</a>, describes ThinKom's VICTS antennas used in Gogo's 2Ku product.  It gives a nice short overview of the technology and what makes it uniquely ideal for commercial air transport and beyond.  James Morra writes, "The antennas were designed by <a href="http://www.thinkom.net/" target="_blank">ThinKom</a>, an antenna design company based in Torrance, Calif. that provides technology for aerospace and other mobile communications. The antennas are unique in that they create beams by mechanically rotating a series of internal plates with precise resonance characteristics...What separates the 2Ku system from more conventional aerospace antennas is that it combines technical benefits from both electronic phased arrays and mechanically steered antennas (including reflectors and flat panels)."
