Computational results of the (a) real, and (b) imaginary parts of the impedance for a single-port G1 spiral with a varying turn number from 3 to 14. Each curve is labeled with the turn number at the first resonance peak. It is noted that the resistances of 3 and 4-turn coils are relatively low at this frequency range and not labeled in (a).
