Abstract (en)

[origin: WO9607214A1] In order to compensate for changes in the resonant frequency of the resonator arising from variations in the distance between the reference distance (dS) and an actual distance (dS+/- DELTA dS) in HF stripline resonators with a stripline (10) arranged at a reference distance (dS) from a metal conductor (11), the stripline (10) is curved. The curvature induces eddy currents in the conductor (11) which reduce the inductance of the HF stripline resonator. The shorter/longer the distance between the stripline and the metal conductor, the smaller/greater the inductance. As the shortening/lengthening of the distance between two conductors also increases/reduces the capacitance of the HF stripline, however, with the appropriate dimensions of the curved stripline, the two effects cancel each other out and the frequency of the HF stripline resonator is virtually stable with the aforementioned distance variations. The two effects cancel each other out and the frequency of the HF stripline resonator is virtually stable with the aforementioned distance variations.
