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 ...

Half of all new cars sold in the U.S. have keyless entry as a standard feature. It’s convenient, but it leaves your car wide open to thieves to either break in or drive the car away, using nothing but ...

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 ...

Paper 403: Measuring magnetic loop antenna performance. Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a ...
