Hey guys,
I am going to design a 27MHz antenna but small size. So i decided to use ferrite rod antenna. I found that most of the resources indicated that an extra capacitor is required to connect in parallel with the ferrite rod antenna to make it in parallel resonance. However, input impedance will become several thousands.
I guess because the input impedance of most of the system that operate in HF band is in several thousands so that it need to be resonated in parallel instead of in series. If the input impedance of such system is small i.e. 50ohm, it is better to use series resonant instead of parallel. Is this statment correct?
Thanks
