Theoretical analysis of the coupling between whispering-gallery dielectric resonator modes and transmission lines
Abstract
A theoretical analysis of the coupling between whispering dielectric resonator modes and one or two transmission lines is presented. The whispering gallery modes of the resonator are described in terms of waves running against the concave boundaries of a cylindrical resonator. A formula is presented for calculating loaded Q. Some possible applications of whispering gallery mode resonators in millimeter wave resonators filters, power combiners, and oscillators are also discussed.
