The invention relates to a wireless video transmission system which is provided with an antenna, wherein the antenna is provided with an antenna body and a metamaterial panel arranged on one side of the antenna body, the metamaterial panel comprises a plurality of layers, and each layer comprises a sheet substrate and a plurality of artificial micro structures arranged on the substrate. According to the wireless video transmission system, the metamaterial panel is added on one side of the existing antenna body, and therefore, most of electromagnetic waves generated by a radiation vibrator of the antenna body are refracted by the metamaterial panel to be converged towards the same direction, the width of a radiation lobe is greatly reduced, the gain of the antenna is remarkably improved, and the signal intensity of the antenna is greatly enhanced; and the wireless video transmission system has the advantages of high transmission reliability, long signal transmission distance, simple structure, small size and low cost.
