This paper introduces a dual-layer medium type microstrip GWG. In the proposed structure, microstrip and metal pillar are placed in different mediums, the movement of the locations between microstrip and metal pillar will not affect each other. Compared with traditional single-layer medium type GWG, this structure simplifies the complexity of the design. Based on the microstrip GWG of dual-layer medium, a crossover device with a central frequency of 28GHz is designed. Two parallel microstrips are connected to realize the directional power of the crossover, the coupling degree within the bandwidth of 4GHz is within 0.5dB, and the bandwidth of 14.3% is achieved. The proposed crossover is a 0dB directional coupler. It can realize the directional distribution of power and it has good coupling, isolation and directional performance. Therefore, crossover can be well applied in the field of microwave technology.
