ADELPHI, Md. -- A new, miniature, low-frequency antenna with enhanced bandwidth will enable robust networking among compact, mobile robots in complex environments. In a collaborative effort between ...

Reflectarray antennas represent an innovative class of planar antenna systems that combine the favourable attributes of conventional parabolic reflectors with the flexibility and compactness of phased ...

Antennas used with ground penetrating radar (GPR) come in different shapes and sizes. The largest antennas typically radiate the lower frequencies necessary to detect the deepest targets. The smallest ...

Today, miniaturized devices require the use of antennas that are smaller than their wavelength. Wide bandwidth microstrip antennas get a lot of interest from designers due to their flexibility and ...

The OM-DW Series ceiling-mount antennas support all popular frequency bands from 860 MHz through 5.88 GHz, eliminating the need to stock multiple antenna frequencies. They tout wide bandwidth ...

Like much of the world, Australia is shifting from traditional analog television to digital broadcasting. This means new set top boxes if your TV isn't already able to pick up digital signals. But ...

Isolation refers to keeping multiple antennas separate from one another to avoid interaction effects. In some devices—especially cell phones, where multiple antennas must be squeezed into a small ...

In recent columns, I've discussed options for TV-transmitting antennas. This month, I'll look at the other end of the path – outdoor TV-receiving antennas. I'll describe desirable attributes for DTV ...

Our Hackaday readership represent a huge breadth of engineering experience and knowledge, and we get a significant number of our story tips from you. For instance, today we are indebted to ...

"Whip" antennas—those long metal rods that used to extend from our cars—look pretty cool in a Smokey and the Bandit kind of way. But for military vehicles, they're not such a great solution. Troops in ...
