This Flat Antenna Could Finally Give Good Plane Wi-Fi.

There's a big problem with the Wi-Fi on airplanes. Because it's such a wonderful idea, the fact that it rarely works well makes it feel
more like an insult than a gift—one you paid for.
This is not the promised land of 21st century work and distraction. Want to stream Netflix? Forget about it. Download that PDF? Sure, just give it 20 minutes.
Part of the problem, says Dr. Nathan Kundtz, is the portion of the radio spectrum the FCC allocates for air-to-ground connectivity, between 300 MHz and 3 GHz.
For in-flight connectivity, "there's only an about 3 MHz-section of that band that's allocated, so there's only so much you can do with that." The answer, then, Kundtz says, is "to open up new types of spectrum." He's talking about far higher frequencies, where things are less crowded. The FCC already allocates some of this territory for these purposes, it's just a matter of tapping into them.
