Electrical engineer Ramachandra Bhat Koodur, who has built one of India’s best ham radio stations in Kavoor, recently installed a high-performing Yagi antenna, a directional antenna with a rotator, on ...

One of the first things that an amateur radio operator is likely to do once receiving their license is grab a dual-band handheld and try to make contacts with a local repeater. After the initial ...

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 ...

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, ...

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 ...

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 ...
