Abstract

This article investigates the performance of a circular antenna with a different proposal from the literature on the application of Firat-based fractal modeling. Thus, the present study proposes modifying the modeling from two to four quadrants in the antenna patch. Two frequencies were chosen for analysis, 2 GHz and 4 GHz, with four iterations applied to both antennas. Next, an appropriate mathematical description for the model is presented, based on previous studies and adding the necessary updates for the new application. The performance of each antenna was verified by the reflection coefficient and miniaturization factors. The simulated results demonstrate the miniaturization potential, with a maximum factor of 18.27%.
