There is a common element to every radio system, be it transmission or reception, and that is the antenna. But even though it is an essential system component, historically it’s been the least ...

We all use antennas for radios, cell phones, and WiFi. Understanding how they work, though, can take a lifetime of study. If you are rusty on the basic physics of why an antenna radiates, have a look ...

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 ...

Fig. 1 | Schematics of the PA-PSO algorithm. (a) and (b) Working principle of the metalens antenna. (c) and (d) Comparison between the traditional PSO and PA-PSO algorithm. The red and blue stars ...

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 ...

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 ...

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 ...

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 ...

Though it was hailed as a triumph for the "Standard Model" of physics – the reigning model of fundamental forces and particles – physicists were quick to emphasize that last year's discovery of the ...

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 ...
