An immediate thought - if the loop is big enough that you don't need the 
lumped loading L, then it's a single turn loop. If some of the L is packed in 
a wound component that doesn't radiate, then you lose (I'm guessing) 
according to the reduction in loop area, and by some function of the ratio of 
(inductance in the loop/inductance in the coil).
