【 摘 要 】

References(21)Cited-By(5)This paper presents a new method to design microstrip array antennas. In this method, non-regular polygonal patches are used and their shapes are determined by genetic algorithm (GA) depending on the design needs. The positions of patch vertexes are optimized by GA. Connecting the vertexes with an incorrect order yields to an invalid patch which its edges intersect themselves. So, ant colony optimization (ACO) is used to find correct connection order of vertexes. This method is used to design an array antenna with low amount of return loss and mutual coupling. Finally, design procedure is verified by simulation.
