In this paper, we investigate a new printed antenna based on the 2D image of a fractal tree-leaf geometry by studying the effect of the\nirregular boundary of the proposed antenna on its radiation characteristics. Both the impedance matching properties and the\nradiation patterns of the antenna are studied over the frequency band 1ââ?¬â??6 GHz. Four configurations are designed by increasing\nthe complexity of the structure, which ranges from iteration 0 to iteration 3. The fractal properties of the proposed tree-leaf\nantenna are then compared to those of a conventional fractal antenna with smooth edges. Following this, the proposed antennas\nare fabricated and characterized experimentally. Finally, results are analyzed and discussed, and a practical application for this\nnew type of antennas is proposed
