Claim:
A method for designing a glass antenna, the method for automatically designing a glass antenna by combining an EM simulation tool with an optimization algorithm, a preparation step of controlling an equivalence coding condition of a glass and a location of an antenna power feeding unit so that a simulation of a glass antenna can be possible through an EM (engineering model) simulator, changing a vehicle structure with a mesh number appropriate for applying an optimization algorithm, and determining a proper initial prototype according to a kind of vehicle and glass size and shape; a performance optimization step of optimizing a glass antenna performance by operating the EM simulator with the optimization algorithm after the preparation step is completed; and a mass production optimization step of redesigning an optimized glass antenna as a final glass antenna shape applicable to a mass production when the optimized glass antenna is obtained after the performance optimization step is completed, wherein the performance optimization step comprises: encoding and decoding the glass antenna shape of the initial prototype by utilizing the EM simulator; filtering a design in which the glass antenna shape or a condition is not suitable; determining cost values which are indexes indicating the performance of the glass antenna; determining a Pareto-Cost value after the simulation of one generation is completed; determining a convergence of the Pareto cost value; and creating a new generation and circulating to the decoding step in case the Pareto-Cost value does not converge, while obtaining the optimized glass antenna in case the Pareto cost value converges.
