The demonstration of a Yagi–Uda nano-antenna that operates at visible wavelengths gives hope for a convenient means of directing radiation patterns from nanoscale light sources such as single ...

I've constructed hundreds of antennae in the past. Bowtie dipole arrays, biquads, parabolic reflector dipoles, straight up yagi, logarithmic yagi, log periodic, heliacal and simple 1/4 whips. So when ...

If you’ve ever cast your eye towards the rooftops, you’ll be familiar with the Yagi antenna. A dipole radiator with a reflector and a series of passive director elements in front of it, you’ll find ...

Yagi antenna can be used at transmission or reception but are more used for transmitters. This antenna is a directional system consisting of an array of a dipole and a reflector and one or more ...

Researchers in Japan have built a nano-scale version of the classic antenna used to pick up TV signals in millions of homes around the world. The device, which is based on the “Yagi-Uda” antenna, ...

A paper published in Nature this week details how researchers have taken a common antenna design and replicated it on the the nanoscale level. When a regular TV aerial that handles radio frequencies ...

The Norwegian Space Centre has announced successful deployment of critical antennas and probes on the NORsat-1 and NORsat-2 microsatellites built by Canada’s Space Flight Laboratory (SFL) and launched ...
