Abstract
The paper introduces a fractal geometry utilizing an Octagonal Split Ring Resonator (SRR) hybrid DRA as its basis. The primary antenna consists of a conventional Octagonal patch, which is then scaled down by 0.5 in the first iteration and further by 0.25 in the second and then the DRA is utilized to enhance its performance. Remarkably compact at 6 × 6.2 cm, the antenna demonstrates effectiveness across frequencies of 5.1, 6.8, and 7.2 GHz notably; it maintains a gain above 3.3 dBi and directivity above 4.1 dBi in all operational bands. Analysis employing surface current and return loss substantiates the impact of the fractal design with DR. These simulations and measured results affirm the proposed antenna's suitability for robust C band wireless applications, offering promising performance in antenna parameters.
