Abstract :
This paper presents a new improved enhanced effective medium method that can be used to evaluate performance of the HIS structure with different patch shapes. This method is a combination of the enhanced effective medium method and the Guass´ law. To validate the proposed method, the surface impedance values of the circular patch HIS structure obtained from both HFSS simulation tool and the presented theory are compared. Close agreement between the results is observed.
