In this article, an innovative structure of a high gain stacked fractal antenna is introduced. This article follows stacking and Sierpinski Carpet concept to achieve wide bandwidth and high gain of the antenna. The proposed design consists of five patches, the driving element is printed on the lower substrate and other four parasitic patches are suspended with dielectric clamps above the driving element. This designed antenna has 550MHz bandwidth with a gain of 10.3dB. As this antenna is operating at 6GHz frequency, this antenna is suitable for C-band applications.
