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-turn ...

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 ...

Fig 3. DockOn’s CPL antenna is based on a collocated magnetic loop dipole and an electric dipole. The dipole moments have to be orthogonal to prevent the two elements from radiating as two separate ...
