Abstract

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.
