This paper presents a novel technique for the tun- ing of high dielectric resonators at microwave and mil- limeter wave frequencies. The resonator is tuned by coupling it to a section of non-resonant microsirip line. An experimental band-rejectfilter with a Q of 550 was tuned using this technique. The resulting tuning range of theJilter was over 18 times its bandwidth. This tech- nique makes it cost effective to tune dielectric resona- tors over a relatively broad range while maintaining a high Q characteristic.
