In order to optimization the design parameters between the antenna matching impedance and structural size, in this paper RBF neural network is used to establish the multivariate nonlinear model of symmetric bending slot antenna between matching impedance and geometric structure parameters;solved long time consuming problem while using full wave analysis tool to calculate. Then the particle swarm optimization algorithm is adopted to quickly found the size of the miniaturization structure with different types of impedance; realize the matching impedance and geometric size of the intelligent optimization. Based on the HFSS software testing, the result of the optimization actual achieve the design ’s requirements. It provides the antenna developers a concise and easy to understand、simple operation and convenient optimization method, to improve the efficiency of antenna design, so as to realize the computer aided intelligent optimization design of tag antennas.
