Even as 5G looms, losing the signal on your phone seems like a headache that will never quite go away. Now, though, a new antenna design could take wireless communications to previously radio dead ...

A group of five Talawanda high school seniors are building a VLF space antenna to monitor changes in ion activity in the atmosphere during the solar eclipse of August 21. Energy from the sun creates a ...

Could a century-old military communication method be quietly protecting our planet from deadly space radiation? NASA’s Van Allen Probes, launched in 2012 to study Earth’s radiation belts, stumbled ...

Using digital techniques has caused a resurgence of interest in VLF — very low frequency — radio. Thanks to software-defined radio, you no longer need huge coils. However, you still need a suitable ...

There's a reason that scuba divers use sign language and that caves and tunnels create radio dead zones. The laws of physics prevent radio signals from penetrating materials like water, soil and stone ...

The Air Force is looking for the next generation of Very Low Frequency communications to maintain contact with its ICBMs and bombers. In particular, the Air Force wants to address the problem that ...

Menlo Park, Calif. -- A new type of pocket-sized antenna, developed at the Department of Energy's SLAC National Accelerator Laboratory, could enable mobile communication in situations where ...

The 4-inch-tall device could be used in portable transmitters for rescue missions and other challenging applications demanding high mobility. MENLO PARK, CA— A new type of pocket-sized antenna, ...

A new type of pocket-sized antenna could enable mobile communication in situations where conventional radios don't work, such as underwater, through the ground and over very long distances through air ...
