Abstract

A novel, hybrid, electrically and mechanically tunable band‐stop waveguide filter is presented. The filter consists of a dielectric substrate on which a ring microstrip element is etched. The mechanical tuning range (the maximum band‐stop frequency that can be attained) is shown to be limited by the distance of the ring element from the conducting waveguide walls. This limitation is overcome by introducing electrical tuning, which is achieved by incorporating varactor diodes on the microstrip ring element. Β© 2004 Wiley Periodicals, Inc.

## Abstract A mechanically tunable microwave band‐stop filter, in which tunability is achieved via a movable dielectric substrate incorporating a conductive ring element is proposed. Experimental results, which are corroborated by numerical analysis, are presented that demonstrate wide tunability w
