“…In this way, an expression for 1 -t 2 which coincides with eqn. 10 is obtained, but A* 2 , is now equal to 1 -\/{P + I) 2 . This offers the possibility of using an experimental scalar technique to make the necessary measurements, preserving the numerical aspects of the data processing.…”

“…One of the most frequently used circuits consists of a dielectric resonator operating in the TE 01(5 mode, magnetically coupled to a microstrip line [1]. It has been used in filters [2] and in stable oscillators [3]. The proper and efficient use of dielectric resonators requires adequate procedures for their characterisation in the actual system.…”

An automatic computer controlled technique is proposed to measure the resonant frequency, loaded quality factor and coupling factor of a dielectric resonator coupled to a microstrip line. The complex transmission coefficient of the system is measured, as a function of frequency, by means of a network analyzer. At each frequency, the reflection coefficient is calculated and its magnitude is processed to obtain the characteristic parameters of the resonator. Estimated errors for Q-and coupling factors are in the order of 1 %, and for the resonance frequency are about 1 part in 10 6 .
