Effects of surface modifications of a cable-network antenna on reducing grating lobe levels are investigated. Some systematic or random modifications of the node positions of the cable-network antenna are introduced and the reductions of grating lobe level are investigated through numerical simulations. The results show that the grating lobe levels are reduced by these surface modifications and the appropriate systematic modifications achieve the reduction of grating lobe level while maintaining the antenna gain. The cable network structure with the appropriate systematic modification was designed using force density method and the feasible tension distribution was achieved.
