Abstract： In this paper， a circular hole array all-dielectric metasurface was designed， which could suppress multipole scattering due to Fano resonance and achieve complete transmission of the incident electromagnetic waves with certain frequency. The experimental results of the circular hole array on the polytetrafluoroethylene ceramic composite substrate show that when the period， circular hole radius and thickness of the metasurface cell structure are 30 mm， 8.5 mm and 1.3 mm， respectively， the transmittance of the incident electromagnetic wave at 8.48 GHz is 93.89%， which is basically consistent with the simulation results. The small shift and decrease of the transmission peak are due to the processing deviation of the experimental sample and the absorption of the sample material to the electromagnetic wave. This all-dielectric transparent metasurface has simple structure， easy fabrication， reliable performance and good application prospects.
