In view of the single curved deformation characteristics of zero Poisson’s ratio (ZPR) honeycomb, Arrow honeycomb with ZPR is applied to the reflecting surface of the spatial parabolic cylinder antenna in this paper. First of all, the loading method for cylinder formation of honeycomb with ZPR is analysed. Then, Abaqus analysis, surface fitting and precision calculation are integrated into the objective function. Antlion Optimization (ALO) algorithm is used to optimize the RMS error of the deformed surface. The analysis results show that it is feasible to apply the honeycomb with ZPR to the reflector of cylindrical antenna, and the accuracy of deformed profile is improved by 45.5% through the ALO algorithm, which proves the effectiveness and efficiency of the ALO algorithm to solve the problem with unknown initial value. The research results are certainly significant for the optimization design of honeycomb with ZPR and the application of ALO algorithm.
