can any one explain what is the difference between spiral inductors with ground plane and that without? (hint: i DONT mean that ground plane is patterned ground shield)
Any object close to a spiral inductor will affect it. If the object is conductive, the inductor field will generate eddy currents in it. A good conductor will change the inductance value, a poor conductor will affect its resistance.
