This promises lighter, more portable communication systems for remote or emergency use, opening the door to flexible, ...

Antennas are mechanical components which either transmit or receive radio frequency signals. For transmission, an oscillating RF electrical current is fed to the antenna's terminals, where the conduit ...

There’s an old saying in the amateur radio community that when it comes to antennas all you need is a piece of wet string. This may be a little fanciful, but it’s certainly true that an ...

Imagine taking the radio frequency properties of the dish antennas you see on rooftops and knitting them into a wearable ...

ELITE 750 - Broadcasts every radio wavelength—AM,FM, LW, SW, SSB and VHF aircraft band frequencies. The 360° rotating AM antenna pulls in even the weakest of signals for full, bold sound.

The electromagnetic field travels from the antenna in all directions and at the speed of light. It travels until it hits your radio's antenna as well as hundreds of other receiving antennas.

Imagine a lightweight sweater or blanket that doubles as a powerful radio-frequency antenna. Engineers at Columbia University ...

After being inspired by The Expanse series, researchers at the Johns Hopkins Applied Physics Laboratory have utilized novel ...
