Learn how a homemade WiFi gun style antenna can boost signal strength and extend wireless range. This DIY project shows the ...

GPS can be a bit complex of a technology – you have to receive a signal below the noise floor, do quite a bit of math that relies on the theory of relativity, and, adding insult to injury, you also ...

In this video, I'm making a DIY Yagi Antenna specifically designed for use with 868MHz LoRa to try and beat my previous ...

Experimental technologies offer elegant, inexpensive solutions. Researchers are studying applications and materials for creating radio antennas that are sprayed onto a surface. Made from commercially ...

Build as described above but omit the reflector. I use such an antenna for UHF (675MHz centre) DVB-T transmissions. It compares very favourably to commercial Yagis. Gain is about 6 dBi and it has two ...

When it comes to electronics, bigger usually isn't better. This is especially true for a new generation of wearable communication systems that promise to connect people, machines and other objects in ...

When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...
