[en] Short mode selective directional couplers for transverse electric (TE) modes travelling in overmoded circular waveguides are described. Directivity is achieved by pairs of holes with destructive interference in backward direction, unwanted modes are suppressed by destructive interference in either directions of the coupling guide. A 28 GHz narrow directional coupler for the TE₀₁ mode (63.4 mm waveguide diameter) with 16 holes and a length of 230 mm shows a directivity of 55 to 100 dB between 27.9 and 28.1 GHz, suppressing the TE₀₂ mode with 35 to 80 dB, the TE₀₃ mode with 30 to 65 dB, and the TE₂₂ mode with 30 to 70 dB.
