From: Suppressing loop current of shielded loops at fundamental resonance
(a) Experimental setup. A double-loop probe measures the loop current. The double-loop probe is connected to a VNA. (b) Tuning capacitors. (c) PCB. An RF shield is installed to suppress the mutual inductance between a loop and the inductor on the board. (d) Circuit schematic of (c).
