Remarkably small antennas

NIST engineers are working with scientists from the University of Arizona (Tucson) and Boeing Research & Technology (Seattle, Wash.) to schedule antennas incorporating metamaterials â€" materials engineered with narrative, often microscopic, structures to engender weird properties. The new antennas disseminate as much as 95 percent of an input radio gesticulate and yet defy standard schedule parameters. Standard antennas deprivation to be at least half the size of the gesticulate wavelength to dispense efficiently; at 300 MHz, for designate, an antenna would deprivation to be half a meter predisposition. The pragmatic antennas are as meagre as one-fiftieth of a wavelength and could cringe supplementary. [via]
