[EN] This article describes different tunable structures
for typical waveguide combline filters. In this context, several
configurations using dielectric tuners have been studied for
resonators, inter-resonator couplings, ...
[EN] The objective of this article is to explore the use of dielectrics to reconfigure remotely microwave filters in rectangular waveguide. To start, we study experimentally the phase shift that is achievable using dielectric ...
