The original parameters were obtained through calculation, and ADS simulation software was also applied. And a model of the Directional Coupler was also built. And based on simulation the initial curve of device was obtained. The model was optimized and an optimized coupler model conforming to design requirement was finally accomplished. And performance analysis, production machining and performance test was performed for this model. And test results showed this design could provide good performance and simple structure. Also k can be integrated easily.
