Abstract

In this paper, Multiple Split Koch Snowflake Fractal is investigated as resonat- ing element. It was found to resonate at 0.77–0.82 GHz, 2.3–2.42 GHz, 3.6–3.7 GHz and 5.3– 6 GHz with center frequency of 0.8 GHz, 2.35 GHz, 3.65 GHz and 5.5 GHz which covers the LTE/WLAN/WiMAX spectrum. The antenna was realized on a FR4 epoxy substrate with dimension 0.08λo × 0.08λo × 0.042λo (30 mm × 30 mm × 1.6 mm). Parametric analysis was per- formed on the dimension of various elements of the antenna. Fractal structure was responsible for multiband resonance and the addition of split element in the fractal enhanced the ability of the antenna to resonate at lower frequency. Further the antenna was fabricated and tested.
