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 ...

Antennas have played a vital role in the field of communications. Wireless transmission and reception of signals have greatly impacted our everyday lives. The Yagi-Uda antenna or Yagi Antenna is one ...

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, ...

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 ...

For the first time, physicists have successfully converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in ...

A new optical antenna could improve the efficiency of devices that handle just a few photons at a time, such as quantum computers and quantum cryptography circuits. The antenna, which receives and ...

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 ...

We’ve heard reports that internet connectivity in Australia can be an iffy proposition, and [deandob] seems to back that up. At the limit of a decent DSL connection and on the fringe of LTE, [deandob] ...

Want to know which way to point your WiFi antenna to get the best signal? It’s a guessing game for most of us, but a quick build of a scanning WiFi antenna using mostly off-the-shelf components could ...

(Nanowerk News) For the first time, physicists from the University of Würzburg have successfully converted electrical signals into photons and radiated them in specific directions using a ...
