A new simpler, cheaper and potentially more effective way to prevent radio antennas from picking up unwanted signals has been created by researchers in the US. With further development, the technique ...

Designing equipment that meets stringent size and mass restrictions for use on aircraft brings extra challenges for instrument developers, as Tamara Clelford explains Antennas are used for a huge ...

In making the most precise measurements ever of the shape of electrons, a team of Harvard and Yale scientists has raised severe doubts about several popular theories of what lies beyond the Higgs ...

PHILADELPHIA—To receive TV broadcasts, you need some sort of antenna. And that antenna can’t just be a paper clip or coat hanger, although both can work sometimes. The antenna must have some physical ...

What's the optimal orientation of an antenna broadcasting and receiving on a wireless access point? Could it be anything other than vertical? Is it dependent on the environment and the surrounding ...

The pursuit of next-generation technologies places a premium on producing increased speed and efficiency with components built at scales small enough to function on a computer chip. One of the ...

Tech blog Anandtech goes hands-on with the iPhone 4, iPhone 3GS, and Nexus One to find out if the antenna issue is unique to the iPhone 4's hardware or software. Erica Ogg is a CNET News reporter who ...
