    • Provided is a method for designing multiband antenna using a genetic algorithm unit linked to an electromagnetic wave analyzing unit and to a computer-readable recording medium for recording a program that implements the method. The multiband antenna designing method can design an antenna having an optimal structure by combining a genetic algorithm, one of global optimization techniques, with a full electromagnetic wave analyzing program Quick Finite Difference Time Domain (QFDTD). The method of the present research includes the steps of: a) at the full electromagnetic wave analyzing unit, analyzing an antenna structure contained in an input file and linking the antenna structure to the genetic algorithm unit; b) at the genetic algorithm unit, generating an initial group that expresses the antenna structure; c) at the genetic algorithm unit, evaluating cost functions by using the antenna structure analysis result; and d) at the genetic algorithm unit, designing an antenna by selecting objects based on the cost functions, mating the selected objects and generating mutants.
