Novel designs of polarization-preserving circular waveguide filters
Published online by Cambridge University Press: 07 January 2011
Abstract
Novel designs of circular waveguide components for lowpass, highpass, bandpass, and bandstop applications are presented. The filters are formed by cascaded TM11-mode resonator sections which share a common axis, thus preserving the polarizations of input signals due to rotational symmetry. Moreover, the filters are smaller than standard TE11-mode bandpass filters. Basic design considerations are discussed with respect to the connection of TM11-mode resonators through circular irises. Design principles for all four filter types are presented and their performances computed by the coupled-integral equation technique (CIET). All filter performances are verified by the commercially available software package μWave Wizard, and structural dimensions are provided.
