It’s thus worth putting in the effort to make a better antenna, and if you’re not fortunate enough to have a lot of space, your best choice may be a magnetic loop. [Robert Hart] takes us ...

If you are a radio amateur, you may be familiar with the magnetic loop antenna. It’s different from most conventional wire antennas, taking the form of a tuned circuit with a very large single ...

An introduction to properties of individual antennas and arrays of antennas. Retarded potentials, dipoles of arbitrary length, radiation pattern, gain, directivity, radiation resistance. The loop ...

The original „donut“ loop antenna did not work seemingly due to a design issue. A scalpel, two tiny wires, and four solder joints rescued it.

2. TRACK Multiple detection loop antennas buried in the track surface and strategically located around the track record the passing time and identification of the radio transponder attached to each ...
