A ceramic waveguide filter, a radio unit, an antenna unit and a base station are disclosed. According to an embodiment, a ceramic waveguide filter comprises a body () that is made of a ceramic material and that has a plurality of resonators each including a blind hole (). The blind holes () of two of the resonators open at a first surface of the body () and extend toward an opposite second surface of the body (). Capacitive coupling between the two resonators is achieved by a coupling structure () on/in a substrate (), to which the body () is attached at the side of the second surface.
