Ferrite antenna com system
The problem with loop antennas made of ribbon cable (or other
multiconductor cable connected this way) is the stray capacitance between turns. The self resonance frequency (without external capacitor) may be below the band of interest, so you can not resonate such antenna with an external capacitor. I found it very useful for design of hard-driven Power MOSFET driver transformator till 400KHz without problems. - Henry |
