We never quite seem to get to one design that can do everything. This copper-foil Yagi antenna might not do everything, but it really seems to tick off the boxes for gain and directionality along ...

A rooftop TV antenna is a great example of the type, called a Yagi-Uda array after its inventors. They set out to create a wireless energy transmission system using radio waves, and found ...

Let there be light - and it was directional: The world's first electrically powered Yagi-Uda antenna was built at the University of Würzburg's Department of Physics. Disclaimer: AAAS and EurekAlert!

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 ...

The RCA Compact Yagi Outdoor antenna is a directional antenna that is best suited for rural areas with hard-to-reach UHF and VHF signals. It’s a great pick if you want to put your antenna in ...

Omnidirectional and directional antennas represented in WiFi Yagi-Uda antennas, which have an active element with accompanying parasitic and reflective elements to create a highly-directed ...

Key aspects of the electromagnetic wave behavior and design of antennas and antenna arrays from wire dipoles and Yagi-Uda antennas above the Earth’s surface to aperture antennas such as horns and ...
