The invention discloses a net-shaped reflecting surface antenna for restraining passive intermodulation in the manner of weaving. The net-shaped reflecting surface antenna consists of cylindrical metal wires of which the diameters are less than 1/50 work wave length, and each weaving base unit consists of two set of orthogonal metal wires; for a linearly polarized emission source, a set of metal wires which are in parallel with one another and are distributed at intervals are arranged along the polarization direction of an electric field and are aimed at a linear polarization direction, and another set of the metal wires which are in parallel with one another are orthogonally woven with the metal wires; and for a circularly polarized emission source, the net-shaped reflecting antenna is crossly woven by concentric circles formed by the metal wires and the metal wires which are diffused along the radial direction. The net-shaped reflecting surface antenna is designed by the means that the occurring probability of the passive intermodulation is gradually increased along the increase of the contact point current, so that the polarization direction of the electric field is always or approximately in parallel with the metal wires along one direction, and the surface current can not pass through contact points of the metal wires along different directions; and therefore, the generation of the passive intermodulation can be restrained. After the net-shaped reflecting surface antenna is adopted, the generation of the passive intermodulation can be restrained in advance when a system is designed.
