FIG. 1.

Sketch of a CPR. Angles indicate the in-plane and out-of-plane orientation of the magnetic field with respect to the substrate. Inset: photograph of the CPR, comprising a center conductor of length and width separated from ground planes by an gap. The center conductor is capacitively coupled to the feed lines by gap of at each end. The meander line is used to confine the whole structure within the long substrate.

FIG. 2.

Dependence of resonant frequency and quality factor on temperature for an overcoupled CPR fabricated on a sapphire substrate.

Image of FIG. 3.
FIG. 3.

(a) Quality factor, (b) sensitivity to magnetic field, and (c) center frequency shift with respect to . The power was measured at the output of the VNA ( corresponds to about on the sample). The measurements were made with the field applied at at various temperatures, two excitation powers and two directions of the field sweep.

Image of FIG. 4.
FIG. 4.

Change in resonant frequency with perpendicular magnetic field for the fundamental, first, and second harmonics. The inset shows the dependence of fundamental frequency shift on the angle at .
