There are plenty of small ESP32-C3 IoT boards with a USB-C connector on the market, and while they all look very similar, antenna designs differ, and less thought-out ones may severely impact the WiFi ...

A new measurement method for the magnetic antenna factor of a small circular loop antenna is proposed and described. It is possible to obtain the magnetic antenna factor of a small loop antenna from ...

The Simple Antenna Modification This involves adding a wire antenna. A 31mm length of 1.0mm silver-plated wire is formed into a specific shape: a small loop at the bottom (approx. 5mm diameter) with ...

Cutting the cord? Finding the best TV antenna can be tricky. From high-gain and 4K-ready to eco-friendly construction, here are the best antennas you can buy.

Determining the radiation efficiency of an antenna is a difficult task that becomes challenging when it is about electrically small antennas. This work investigates the applicability of the Wheeler ...

MagneticLoop DIY Magnetic loop antenna for WARC bands (17m and 12m) This project show how to motorize the CV of a magnetic loop. It contains : ...

A small compact feed antenna has been designed to meet the need for a 2 to 14 GHz frequency of operation for a reflector antenna. The feed has a nearly constant gain of 11dBi up to 10GHz and a slight ...

Magnetic loop antennas are great if you are limited on space since they are just a potentially small loop of wire. The problem is, they are sharply tuned. You normally have an adjustment capacitor … ...
