We present the coupling between a strip conductor of finite thickness and a cylindrical dielectric resonator (DR) for the TE 01δ mode, in a suspended substrate environment. By incorporating induced emf on both sides of the conductor, we develop an analytical formulation for the external quality factor (Q e ) to give a finite‐thickness effect. Theoretical data for Q e between DR and microstrip line as a special case show good agreement with experimental data presented in the literature. We then extend this procedure to calculate the Q e between a DR and two important transmission‐line structures: suspended strip line and inverted microstrip line, which are suitable for millimeter‐wave applications. © 1996 John Wiley & Sons, Inc.
