Abstract
A waveguide filter including a coupling window for generating negative coupling includes: a plurality of resonators including a substrate block; and the coupling window provided between the plurality of resonators for coupling, wherein a length of a dimension element of the coupling window is equal to or greater than half a working wavelength of the waveguide filter. The waveguide filter may reverse a coupling polarity between resonators to generate negative coupling.
