Abstract :
The current method for evaluating the effective dielectric constant ¿¿e f of microstripline (or coaxial line) has been found to be error susceptive. The error analysis has shown the limitations on the bandwidth of measurements and physical restrictions to be imposed on the test jigs to avoid anomalous values of propagation constant. The practical measurement of ¿¿e f has been carried further to characterise OSM¿¿244¿¿4ASF connectors and HI¿¿Q 100pF DC block chip capacitor in the 2¿¿4 GHz range.
