| Summary: | This paper is to propose a multiband matched
bandstop filter. A lossy resonator is proposed and it
demonstrates the concept and design of a perfectly
matched bandstop filter with a matched response. . The
design is based on a half wavelength (λ/2) and quarter
wavelength (λ/4) resonator with gap coupling, parallel with
an all-pass nominally-90º-phase-shift element, which can
be optimized to achieve high Q-factor. The filter design is
cascaded to achieve multiband isolation. Theoretical
analysis together with experimental results are presented
in this paper. |
