This MI2 Fractal Loop antenna file was created by Dr. Steven Best, VE9SRB
The MI2 Fractal Loop antenna itself was designed by Dr. Nathan Cohen, N1IR. Results of Dr. Cohen's work on the MI2 Loop were presented in several Communications Quarterly articles. The most notable article was entitled: "Fractal Loops and the Small Loop Approximation", Winter 1996.
According to Dr. Cohen's results, the MI2 Fractal Loop has a resistance of 26 ohms at the first resonance. The gain of the antenna at resonance is 2 dBi.
The results determined from EZNEC with this MI2 model are consistent with Dr. Cohen's work.
The first resonance occurs between 15.15 and 15.16 MHz with a resistance of 28 ohms. The antenna gain is 1.83 dBi. The 2:1 SWR bandwidth wrt 50 ohms is approximately 1.05%.
Note that the wire radius in this model is 3.2 mm. This is important for comparing antennas as wire radius will impact resonant frequency.
The MI2 Loop antenna as described in this model has a total wire length of 27.564 m and an aperture size of 2.8 m (X) by 2.662 m (Y).
