Miniaturized high rejection C-band planar band-pass filter for a spatial application

This paper describes an original planar solution used to realize a high rejection planar filter in C-band for a given spatial application.

Description
Summary:This paper describes an original planar solution used to realize a high rejection planar filter in C-band for a given spatial application. Because of the very strong specifications for the filter, a classical topology was forbidden. The proposed solution is based on the use of dual behavior resonators in which high frequency stubs are oversized to increase the rejection. Low-pass structures are also integrated in order to suppress spurious resonances. Both, simulated and experimental data are compared. Temperature measurements are also presented.
