Spiral artificial electromagnetic structure suitable for broadband circular polarization wireless energy receiving

The utility model discloses a spiral artificial electromagnetic structure suitable for broadband circular polarization wireless energy reception. The spiral artificial electromagnetic structure comprises a plurality of resonance units which are arranged in an equal-row and equal-column manner along an orthogonal direction. Each resonance unit comprises a substrate, an insulator and a spiral line;wherein the insulator is fixedly embedded in a substrate through hole of the substrate; the insulator is provided with a plug wire hole which is a through hole. The spiral line is arranged on the substrate, and one end of the spiral line is fixedly inserted into the plug hole; the spiral line is provided with a plurality of circles of spirals and comprises a lower spiral part and an upper spiral part; the radiuses of circles of spirals of the lower spiral part are equal and the screw pitches are linearly gradually changed; the radiuses of all circles of spirals of the upper spiral part are equivalently decreased progr
