Abstract :
We have studied the measurement of low dielectric loss materials using a parallel plate resonator and ceramic cavity method. The measurement error of dielectric constant was 0.03%, due to reasons such as the difference diameter of the loop and the air gap effect. Reliable Q×f values were determined with a probe size of less than 2 mm and an insertion loss of more than 25 dB. Surface roughness could be reduced to less than 0.05 μm. Measurement accuracy of the temperature coefficient of resonance frequency was improved to within ±0.2 by using the ceramic cavity
