Abstract: This paper presents an adaptive Koch-curved Log-Periodic Dipole Array (LPDA) antenna design that enhances broadband performance and radiation efficiency through element-wise fractal height tuning. By integrating Koch fractal geometry into individual dipole elements, the antenna achieves compact size reduction while maintaining wide frequency coverage. Adaptive height variation across elements improves impedance matching, gain stability, and directional radiation characteristics. This tuning method enables precise control of current distribution, resulting in optimized bandwidth and reduced return loss. Compared to conventional LPDA designs, the proposed Koch-curved structure offers better miniaturization and improved electromagnetic performance without adding significant fabrication complexity. Simulation results demonstrate improved voltage standing wave ratio (VSWR), consistent gain, and stable radiation patterns across a broad frequency range. The design is well-suited for modern wireless communication systems, including broadband, radar, and spectrum monitoring, highlighting the effectiveness of combining fractal geometry with adaptive structural tuning.
