Abstract :
This paper presents the development of a multiband fractal antenna based on the Sierpinski triangle. By changing the structure, upper bands may be selected over a number of multiple frequencies. This property is based on Pascal triangle properties. The paper also develops an explanation of why fractal antennas have constant radiation properties at multiband frequencies. Finally, some impedance and radiation measurements are presented.
