A new kind of inter-digital Defected Ground Structure(DGS)coplanar waveguide adopting inter-digital capacitor to replace slot capacitor in regular structure was put forward,and inter-digital capacitor DGS can enhance coupling of capacitor better and improve the characteristics of DGS.Then inter-digital DGS coplanar waveguide was modeled,and dimensions and operating frequency of DGS were sampled,which was taken as the input samples of multi-layer perceptron,BP(back-propagation) algorithm was adopted to train multi-layer perceptron and get neural network model of suitable samples.Neural network model which has been trained has a lot of characteristics in the simulation such as fast calculation,high design precision,strong generalization ability,well consistency of simulation and experiment result.Those validate the efficiency of neural network and supply theoretical basis for circuit design.
