alt Hacker NewsThe thing about the article is that the new patent is basically the same as the almost 20yo design that the author got when a lab closed shop and he asked nicely to have it.
He also says that the "original" design was also not so original as there are previous publications with similar designs.
The antenna itself is just an antenna that works well over a very broad RF spectrum.
So no one has done anything wrong, but researchers find it difficult to understand the breadth of prior research and therefore end up duplicating it?
