As researchers around the world race toward the realization of 6G wireless communication systems, the need for antennas that can dynamically adapt to ever-changing signal environments has never been ...

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 ...

Antennas have played a vital role in the field of communications. Wireless transmission and reception of signals have greatly impacted our everyday lives. The Yagi-Uda antenna or Yagi Antenna is one ...

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!

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 ...

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 ...

A new optical antenna could improve the efficiency of devices that handle just a few photons at a time, such as quantum computers and quantum cryptography circuits. The antenna, which receives and ...
