Abstract

In this paper, an analytical model for the tapered coupler with large dimension is presented based on BPM. Affections of the length and the angle of the taper section for the coupler on the insert loss and split ratio are discussed in details. According to the results of simulations to the tapered couplers with different lengths and angles, some conclusions are obtained as follows: The amplitudes of the field vary with the change of the lengths and the angle of the coupler. And the center of the field deflects in the plane. According to the change of above relation, optimum length and angle are calculated. Aware with the influence caused by these parameters, it is practical significant to design the coupler in order to avoid the power loss.
