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 ...

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 ...
