A new type of broad-wall directional coupler is developed.By eigenvalue approach and odd-and even-mode approach the relationship of the coupling value and the dimension of the coupling section and the phase relationship of the output ports are presented.Mode-matching theory is applied and any additional tuning elements are not needed.The experimental data demonstrate the good performance.
