Fractal Antennas--to the Universe

[Phil]

I guess the US Gumment released another Roswell file, huh?

With FPS, antenna placement and tuning are minor issues. In addition the gain of the FPS antenna depends solely on the area, and not how separate antennas are attached and ‘phased’. The FPS approach also boasts that it is contactless and componentless.

There’s no direct connection or feed. Each of these little antennas add up to make the antenna analogy of a fly’s eye. Covering one has no effect on the others. The problem of hand- smothering the antenna on smartphones, tablets, and other devices now becomes a thing of the past: the antenna has ‘self configured’.

Adds Cohen: ”We have to start looking at surfaces such as the back of a smartphone, wallpaper, a wallet, a printer, a washing machine, or a pill bottle, as a great place to embed an FPS and make the wireless internet of things a reality. The antenna is now no longer a compromising issue. There is a freedom of placement and use that is unprecedented in new applications. Put simply, whenever you see a surface, you can now think ‘antenna’’.
