One of the posters at the phys.org site said, “Warning: Antenna products and research are subject to more snake-oil salesmanship than most other fields,” and I think he’s probably right. I was excited because of the thing about symmetry breaking. I thought some new physics had been discovered. Should’ve known better.
Much truth here. Remember all the hype about fractal antennas? People claimed they would violate Wheeler and Chu's limits on electrically-small antennas. Well, they didn't, and in some cases, they didn't even work as well as previous electrically-small antenna designs.
