Together with his colleague Hidetsugu Yagi, Uda experimented with different configurations. They eventually replaced the loop antenna with a simple dipole, and added additional elements ...

The design of Yagi-Uda antennas is based on a simple principle: a metallic wire resonates strongly if its length matches half of the relevant wavelength. To tune into TV and radio wavelengths ...

Yagi and Uda showed that a single circuit can generate currents in several metallic elements, paving the way for the design of simple and cost-effective multi-element antennas for both the ...

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, ...

To develop the full potential of directional control by nanoparticles, we take our inspiration from radiofrequency (RF) technology, where Yagi–Uda ... antennas show, even very simple ...

A quantum dot drives an optical Yagi-Uda antenna giving a highly directed beam of single photons. This image relates to an article that appeared in the Aug. 20, 2010, issue of Science, published ...
