The demonstration of a Yagi–Uda nano-antenna that operates at visible wavelengths gives hope for a convenient means of directing radiation patterns from nanoscale light sources such as single ...
[Tommy Gober] built this Yagi-Uda antenna that has some handy design features. The boom is a piece of conduit with holes drilled in the appropriate places. The elements are aluminum arrow shafts; a ...
A paper published in Nature this week details how researchers have taken a common antenna design and replicated it on the the nanoscale level. When a regular TV aerial that handles radio frequencies ...
Researchers in Japan have built a nano-scale version of the classic antenna used to pick up TV signals in millions of homes around the world. The device, which is based on the “Yagi-Uda” antenna, ...
Nanotechnology offers the promise of a new wave of sensors and optical components, but the tiny sizes involved can make it difficult for users to exchange information with these devices. Now, ...
BEDFORD, Mass.--(BUSINESS WIRE)--Fractal Antenna Systems, Inc. (FRACTAL) today announced upcoming issuance of a fundamental patent on unidirectional antennas, that replace existing applications with ...
My 200m long, 2.4GHz wireless network link doesn't have a clear line-of-sight. It works well enough in good weather, but with wet or snowy or blowy foliage, it can become unusable. Since the current ...
