The antenna was tested with a Reyas RYLR998 module acting as a base station, with the DIY Yagi hooked up to a RYLR993 module in the field.

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 ...

Physicist and frequent eFlea participant Eric Einarsson built a yagi antenna to boost the reception and transmission distance for his brother’s cell phone. Eric writes: Here is some information and ...

We have seen DIY Yagi antenna designs before but what makes this construction so interesting is that the elements come together using bits of cut metal tape measure sections.

Fortunately, for the system integrator, 160 MHz Yagi antennas are available from several manufacturers as a finished, off-the-shelf product. Figure 3 shows how the four Yagi antennas were precisely ...

A Yagi–Uda directional antenna — the work horse of radiofrequency communications for more than 60 years — has now been demonstrated at visible wavelengths. An array of appropriately tuned ...

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 ...
