Wideband loops work by extracting signal current independent of frequency. You will find the theory completely different from traditional tuned loops.  Read more

Whether we are using an actual magnetic loop antenna or simulating an equivalent circuit, we need to understand how a signal voltage develops across the loop. Where does it come from?  Read more

Magnetic loop antennas are often called constant current loops, which means received signals provide a uniform current flow around the entire loop. Is this assumption realistic?  Read more

Tuned loops magnify voltages like magic. We need to understand how tuned loops work before moving on to un-tuned or wideband loop antennas.  Read more

Your magnetic loop equivalent circuit is the engine under the hood for simulating the performance of an entire wideband active loop antenna. Here’s what it looks like.  Read more

Before I start experimenting, it was time to collect some prototype magloop baseline data. My antenna analyzer come in handy.  Read more

So, my journey begins, starting with a prototype magnetic loop assembly. A starting point for what’s to come, and maybe even part of my finished product.  Read more
