Fractal Antenna Systems announced that it has filed a patent for a unique antenna technology called fractal plasmonic surfaces (FPS) to improve wireless antennas. This technology is an economical solution to offer wideband ability with other novel features.
The FPS takes advantage of the utilization of fractals that are complex geometric structures produced by applying and expanding a basic pattern. A doily-like surface layer is made by tightly placing the fractals in a novel antenna method. This device is a metamaterial with unprecedented electromagnetic attributes.
Prior to the FPS discovery, antennas were systems, which had high sensitivity towards their position and surroundings and set apart to a particular location. The FPS method makes antenna tuning and placement problems insignificant. Moreover, the advantage of the FPS antenna relies entirely on the area and not on the phasing and attachment of the separate antennas. The FPS method is contactless and has no components.
Nathan Cohen, who invented the novel FPS technology, stated that the FPS is a small antenna that reproduces itself throughout a layer using plasmons. It has no direct feed or connection and these tiny antennas combine together to form an antenna system similar to a fly’s eye, he said. Enclosing one antenna has no impact on the others and hand-smothering problem of the antenna on tablets, smart phones and other instrument is now eliminated, as the antenna is self configured.
Cohen further said that the FPS can perform the work of numerous individual antennas due to its wideband ability. The FPS can be entrenched on the surfaces, including the backside of a wallet, wallpaper, smart phone, a printer, a pill bottle, or a washing machine, to realize wireless internet, he said.
