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, ...

Directional antennas convert electrical signals to radio waves and emit them in a particular direction, allowing increased performance and reduced interference. This principle, which is useful in ...

The project uses a 4-element Yagi-Uda and some blinking lights at the top for transmission to create a miniature antenna tower project. The project uses a 4-element Yagi-Uda and some blinking lights ...

(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 ...
