Abstract :
Frequency swept input impedances and Q factors of different sized balanced tuned loop antennas have been measured over their tuning ranges. A simple circuit model, with a dominant radiation resistance proportional to frequency and loop area, agrees well with measurements. Conductor losses, dipole modes, and environmental effects are separately identifiable
