[Hits: 1033 | Votes: 7 | Rate: 5.14] Antennas : Magnetic Loop
- Thinking about Ideal Loops
- Loop antennae have been used from ELF to UHF since the beginning of radiocommunications. At low frequencies, the main problem for loop antennae is to have enough sensitivity; the antenna being very small respect to the wavelength the collected energy is also small. To increase the output level the loop may be made resonant, so loosing it%u2019s intrinsic aperiodic characteristics.
