The invention discloses a magnetic induction wave generation structure based on coplanar waveguides, and the structure comprises the coplanar waveguides, a dielectric plate, and opening resonant rings. The number of coplanar waveguides is two, and the central conduction bands and grounding plates of the coplanar waveguides are distributed at the left and right sides of the front surface of the dielectric plate. The right end of the left coplanar waveguide is in a circuit-break state, and the left end of the right coplanar waveguide is in a circuit-break state. The lengths of the central conduction bands of the two coplanar waveguides are both greater than a half of the length of the dielectric plate. Meanwhile, the two coplanar waveguides are vertically set in a staggered manner. The backsurface of the dielectric plate is periodically provided with some adjacent opening resonant rings, and the central line of the first opening resonant ring in the lateral direction is consistent withthe central line of an outer slit between the central conduction band of the coplanar waveguide at an input signal side and the grounding plate. The last opening resonant ring is across an outer slitbetween the central conduction band of the coplanar waveguide at an output signal side and the grounding plate. Compared with the prior art, the structure is based on the coplanar waveguides, and facilitates the parallel installation of other elements.
