In this paper, an improved directional coupler with strip-loaded is designed. The isolation of the directional coupler is improved by loading metal strip lines. The theoretical analysis and simulation results verify the correctness of the design method. The results show that the proposed directional coupler with strip- loaded can improve the isolation of the coupler by 15dB without obviously affecting the insertion loss and coupling.
