We don’t know if [OH8STN] has a military background, but we suspect he might since his recent post is about a “DIY Man Portable Magnetic Loop Antenna.” “Man-portable” is usually a military designation ...

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 ...

This 4-part report discusses antenna fundamentals and the various types of antennas used for short range devices. Fundamentals are presented along with practical design principals. It is excerpted ...

Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a need to measure the associated electromagnetic field ...

PHILADELPHIA—To receive TV broadcasts, you need some sort of antenna. And that antenna can’t just be a paper clip or coat hanger, although both can work sometimes. The antenna must have some physical ...
