A Dielectric Resonator Bandstop Filter

This paper presents a new analysis predicting accurately the external quality factor and scattering matrix parameters S/sub ij/ of the TE/sub 01p/ cylindrical resonator mode, coupled with a microstrip line for arbitrary locations of the resonator and the line, The results obtained are used to realize a Tchebyscheff bandstop filter. Experimental and theoretical results are also included.
