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 ...

If you have done any sort of radio work you probably have a fair idea about what antennas do. It is pretty easy to have a cursory understanding of them, too. You probably know there’s something magic ...

High bandwidth and throughput maritime broadband services are most commonly enabled by one meter (3.3 foot) Ku-band stabilized VSAT antennas like the SAILOR 900 VSAT. This year though, in parallel to ...

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 ...

North Carolina State University researchers have used a laser to create the first demonstrated plasma beam antenna, a tunable ...

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 ...

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 half-century ago, a radio telescope in Holmdel, N.J., sent two astronomers 13.8 billion years back in time — and opened a cosmic window that scientists have been peering through ever since. 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 ...

If you’ve purchased a new car in the last decade, you probably also own a mobile satellite antenna – albeit for satellite radio. These antennas became standard issue for new automobiles because they ...
