The Underestimated Magnetic Loop HF Antenna - Nonstop …
www.nonstopsystems.comA self-resonant antenna might be thought of as being "optimally efficient". Smaller loops require additional series or shunt capacitance to tune them to resonance so that the impedance presented to the feed becomes real, i.e. R +/−j0. In a self-resonant loop,it is clear that the standard small-loop theory breaks down.
