Dielectric resonator with discrete electromechanical frequency tuning

  title={Dielectric resonator with discrete electromechanical frequency tuning},
  author={G. Panaitov and Roland Ott and N. Klein},
  journal={IEEE Transactions on Microwave Theory and Techniques},
A novel approach for discrete frequency tuning of dielectric resonators based on electromechanical actuators such as the microelectromechanical system is presented. The concept is based on the intermodal coupling between the TE/sub 01/spl delta// mode of a cylindrical dielectric resonator and the radially arranged planar slotline resonators. The resonance frequency of the dielectric resonator is changed by switching a resistive load at the open end of each quarter-wave slotline resonator… CONTINUE READING
