With these antennas; how does the signal flow through the glass?

Is it also possible across other bands; like 2.4GHz Wi-Fi signals?

  • \$\begingroup\$ No. It's near field coupling at the base of the antenna pod. \$\endgroup\$ – Janka Oct 10 '16 at 19:29
  • \$\begingroup\$ For lower frequencies, magnetic coupling is probably more efficient than that very small-value capacitor with a wide plate spacing (through the glass). \$\endgroup\$ – Richard Crowley Oct 10 '16 at 20:15

The glass acts like the dielectric of a capacitor, with the plates being the structures stuck on opposite sides of the glass, I think...
