A technique is proposed to extend the bandwidth of a finline at millimetre-wave frequencies. Instead of mounting the slotline in the E-plane in the centre of the waveguide, the slotline is positioned in a plane where the electric field of the TE20 mode is zero. The bandwidth enhancement is calculated analytically and confirmed by rigorous 3D electromagnetic simulation.
