Non-conventional Multiband Patch Antenna Design with Filtering Aspect Based on Genetic Algorithm

ABSTRACT

This paper addresses the multiband patch antenna design using an improved straightforward method based on genetic algorithm. Starting from a random matrix of squared pixel shapes, the GA optimizes the final design in order to obtain desired specifications, for instance: good impedance matching in required frequency-bands and rejection of undesired bands by integrating appropriate filter. The program is implemented with visual basic script integrated in CST software. The method overcomes the classical design way since the optimized design can be automatically achieved without interfering with designer (independent conception). Validation of the proposed procedure is carried out through simulations and measurements of two patches (dual and tri-band) for WiMAX, WLAN, and X-band applications. Obtained results are in good agreement and demonstrate the effectiveness of the proposed design method.
