The present disclosure relates to a waveguide section (101) comprising at least one air-filled waveguide conducting tube (104; 104a, 104b, 104c, 104d) having a longitudinal extension (L1). Each waveguide conducting tube (104; 104a, 104b, 104c, 104d) has an electrically conducting inner wall (106) and comprises at least one set of at least two electrically conducting integrally formed protrusions (107; 107a, 107b, 107c, 107d). Each protrusion (107a, 107b, 107c, 107d) is electrically conducting and comprises a corresponding plate part (109; 109a, 109b, 109c, 109d) that is adapted to form a capacitance (C1, C2, C3, C4; C10; C11) with at least one other plate part in the same set of protrusions (107; 107a, 107b, 107c, 107d) for each set of protrusions (107; 107a, 107b, 107c, 107d), whereby an RF, radio frequency, signal passing via a corresponding waveguide conducting tube (104) is arranged to be electromagnetically filtered.
A waveguide section comprising at least one air-filled waveguide conducting tube having a longitudinal extension, each waveguide conducting tube having an electrically conducting inner wall and comprising at least one set of at least two electrically conducting integrally formed protrusions, wherein each protrusion is electrically conducting and comprises a corresponding plate part that is adapted to form a capacitance with at least one other plate part in the same set of protrusions for each set of protrusions, wherein a radio frequency signal passing via a corresponding waveguide conducting tube is arranged to be electromagnetically filtered.
