There is no way to cover all the important concepts of directional antennas in a single column. There have been many voluminous tomes written about this subject. This month we will look at some of the ...

Directing the fluorescence from nanoscale emitters such as single molecules and single quantum dots is a key factor in a wide range of applications, from the efficient detection of molecules for ...

Abstract: In this letter, a structure that can flexibly regulate omnidirectional/directional ablation zones is proposed. By fine-tuning the electrical length of tri ...

We may receive a commission on purchases made from links. If you've ditched cable for good, the first place you should look for an alternative is over-the-air television — it offers some of the same ...

Abstract: We investigate the effect of a directional antenna in wireless sensor networks from the perspective of network lifetime extension. Previous studies on wireless sensor networks have assumed ...

If you read old antenna books, you’ll probably see the idea of phased vertical antennas. These use certain lengths of coax to control the phase of a signal going to three verticals in a triangular ...

[Multi-Directional Reception] This smart TV antenna offers multi-directional reception, allowing installation on the roof, balcony, attic, or tabletop. Indoor or Outdoor. Its adaptability makes it ...

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

Cord-cutting has become synonymous with dropping cable and satellite subscriptions in favor of streaming video services. That leaves a lot of live television on the table, which you can get for free.
