It would if this was actually mm-wave 5g. The article says this antenna only functions in the sub 5ghz range, which makes a lot of sense.

Most modern windows use an aluminuzed coating for UV reflection (usually called low-e glass), which surprise surprise, is absolutely great at attenuating mm-wave frequencies, making windows pretty much the worst possible place on a building to place an antenna.

But, turns out most people also dont need gigabit wifi for their phones and other devices, so true mm-wave 5g seems to mostly be reserved for wireless home internet at the moment.
