The only way to determine the characteristics of an antenna is to measure its performance since theory alone cannot predict the actual results. The fields generated by antennas are extremely complex ...

In this application note we will explore antenna theory and design using EZNEC, an easy-to-use antenna simulator. We will measure the antenna’s characteristic impedance through our application board.

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 to ...
