Abstract: A novel three-in-one waveguide resonator is proposed in the paper. The resonator is composed of three rectangular partial-height posts inserted along a rectangular waveguide cross-section. A pair of posts is mounted symmetrically whereas the third antipodal post is centered. The resonator provides a bandstop response if all the posts are of equal height. Both singlet-type and pseudoelliptic characteristics are achieved if one of the posts differs by its height. Both symmetric and asymmetric configurations are considered. Besides, it is demonstrated that the asymmetric resonator acts as a switching waveguide filter providing the ON and the OFF states to allow/block the signal propagation in a narrow vicinity of a given frequency. A parametric numerical study is performed in order to demonstrate a transformation of the response Measurement data are presented for a single-standing resonator and a two-section pseudoelliptic filter in WR90 waveguide.
