Based on approximation of the half-wave field distribution in the slots, an expression is derived for internal mutual conductance of closely-spaced slots, which form a double inclined slot in the narrow wall of a rectangular waveguide. The narrow wall has cut-outs reaching the broad wall. With the use of the method of induced magnetomotive forces, a mathematical model is devised for calculating the energy characteristics of the double slot. The impact of angle of inclination of the slots, dimensions of the cut-outs, slot width, and distance between the slots, on the frequency responses is shown. The results obtained attest that the double slot shows a much lower reflection factor in the waveguide channel.
