摘要

In this paper, a square shaped fractal antenna is designed. The patch has the dimensions of 20 mm x 20 mm. The two iterations are done using reverse fractal geometry. The antenna resonates at three frequency bands which are 4.3719 GHz, 7.777437 GHz and 10.6734 with gain of 1.1974 dB, 4.2745 dB and 4.7233 dB respectively at resonant frequencies. The measured bandwidths are 185 MHz, 198 MHz and 386 MHz at resonant frequencies. After fabrication the antenna resonates at 4.08 GHz, 7.545 GHz and 10.24 GHz with good matching. The square shaped fractal antenna finds its Wi-Fi and WiMAX communication. The measured results are analysed with theoretical results as well as with mathematical analysis which all are in good agreement with each other.
