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

Constant Current Loops – Fact or Fiction
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
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
Magnetic Loop Equivalent Circuit
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
Prototype Magloop Baseline Data
Before I start experimenting, it was time to collect some prototype magloop baseline data. My antenna analyzer come in handy. Read more
Prototype Magnetic Loop Assembly Made and Mounted
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
Wideband versus Narrowband Mag Loops
Once and for all, let’s understand wideband versus narrowband mag loops. It’s a case of open and closed, circuits that is. Read more
Magnetic Loop Performance as Transducers
You will find a lot of confusion about magnetic loop performance, in particular about how they work differently from normal antennas. Let’s dig in. Read more
Aluminum Core PEX Loop Antenna Material
You can make an aluminum core PEX loop antenna easily. This material is cheap, lightweight and easy to form a permanent loop shape. But hard to find! Read more
Diversity Antennas Vision – Finding My North Star
I built my diversity antennas vision around two wideband loop antennas, at least 100 feet apart, all connected with shielded CAT 7 cable for signals and power. Read more
