In this paper, a metasurface structure with dual-layer structure was designed. Two vertical metal bars and three U-shaped metal patterns are prepared on substrate of printed circuit board (PCB). By analyzing the transmission comparison with partial of the structure, it was analyzed that the reason for the multiband analogous electromagnetically induced transparency (EIT) of the structure is obtained by multimode coupling, and the resonance mechanism of the structure was analyzed by multipole scattering theory. By analyzing the electric field distribution of the structure, the physical mechanism of analogous EIT generation of the structure is obtained. The influence of the structure parameters on analogous EIT phenomena is further analyzed. By comparing the measured results with the calculated results in a microwave anechoic chamber, the results are in good agreement. The structure has potential applications in multiband filter, refractive index sensor, and microwave devices.
