The invention discloses a low-sidelobe gap waveguide slot antenna based on artificial surface plasmon, which comprises a first metal layer and a second metal layer which are oppositely stacked, and a gap is arranged on the joint surface of the two metal layers. One end of the antenna is electrically connected to a first waveguide port having a receiving / transmitting signal, and the other end is connected to the radiation opening as a radiation / receiving end of a radio frequency signal. The antenna comprises a horizontal waveguide channel and a vertical waveguide channel, and a matching branch knot is arranged in the horizontal waveguide channel. And an artificial surface plasmon structure is arranged on the outer side of the side wall of the horizontal waveguide channel. By arranging the artificial surface plasmon structure, when the gap exists between the first metal layer and the second metal layer, electromagnetic energy is bound around the artificial surface plasmon, and therefore it is guaranteed that the electromagnetic energy can be completely transmitted in the expected direction. The antenna scheme provided by the invention has great advantages on assembly tolerance redundancy and cost control during mass production.
