Modified Edge Fed Sierpinski Carpet Miniaturized Microstrip Patch Antenna

Abstract

This paper presented a modified edge fed Sierpinski carpet microstrip patch antenna for antenna miniaturization. The proposed design was etched as Sierpinski carpet to lower the antenna resonant frequency, which is used to reduce the conventional patch antenna size. After the Sierpinski carpet second iteration, the proposed antenna was modified by replacing the rectangular slot in the middle of the patch with a circular slot. Simulation results showed that the proposed antenna achieved 46.5% size reduction when compared with the main patch antenna without affecting the resonant frequency and radiation patterns.
